Conditions and exceptions in mail flow rules (also known as transport rules) identify the messages that the rule is applied to or not applied to. For example, if the rule adds a disclaimer to messages, you can configure the rule to only apply to messages that contain specific words, messages sent by specific users, or to all messages except those sent by the members of a specific distribution group. Collectively, the conditions and exceptions in mail flow rules are also known as predicates, because for every condition, there's a corresponding exception that uses the exact same settings and syntax. The only difference is conditions specify messages to include, while exceptions specify messages to exclude.
Most conditions and exceptions have one property that requires one or more values. For example, the The sender is condition requires the sender of the message. Some conditions have two properties. For example, the A message header includes any of these words condition requires one property to specify the message header field, and a second property to specify the text to look for in the header field. Some conditions or exceptions don't have any properties. For example, the Any attachment has executable content condition simply looks for attachments in messages that have executable content.
There is specifically not an easy way to do this. If you could send a message to a computer by just knowing an IP address, wouldn't every advertiser and spammer on the planet want to do this and do it often? Jul 21, 2020. IP address range: For example, 192.168.0.1-192.168.0.254. Classless InterDomain Routing (CIDR) IP address range: For example, 192.168.0.1/25. In Exchange Online PowerShell, you can specify multiple IP addresses or ranges separated by commas. ManagementRelationship: Single value of Manager or Direct report (DirectReport). If one computer knows another's IP but not its MAC and needs to send data, it will send a command called  to MAC addresses FF-FF-FF-FF-FF-FF to which the other computer replies subnet mask the IP numbering system must use a  to give each computer on the network a way to recognize if a packet is for the LAN or WAN.

 Conditions and exceptions for mail flow rules in Exchange Online The tables in the following sections describe the conditions and exceptions that are available in mail flow rules in Exchange Online. The property types are described in the Property types section.
Notes:
After you select a condition or exception in the Exchange admin center (EAC), the value that's ultimately shown in the Apply this rule if or Except if Free horse racing games no download. field is often different (shorter) than the click path value you selected. Also, when you create new rules based on a template (a filtered list of scenarios), you can often select a short condition name instead of following the complete click path. The short names and full click path values are shown in the EAC column in the tables.
If you select [Apply to all messages] in the EAC, you can't specify any other conditions. The equivalent in Exchange Online PowerShell is to create a rule without specifying any condition parameters.
The settings and properties are the same in conditions and exceptions, so the output of the Get-TransportRulePredicate cmdlet doesn't list exceptions separately. Wordweb pro 3 0 – comprehensive thesaurus and dictionary. Also, the names of some of the predicates that are returned by this cmdlet are different than the corresponding parameter names, and a predicate might require multiple parameters.
 Senders For conditions and exceptions that examine the sender's address, you can specify where rule looks for the sender's address.
In the EAC, in the Properties of this rule section, click Match sender address in message. Note that you might need to click More options to see this setting. In Exchange Online PowerShell, the parameter is SenderAddressLocation. The available values are:
Header: Only examine senders in the message headers (for example, the From, Sender, or Reply-To fields). This is the default value.
Envelope: Only examine senders from the message envelope (the MAIL FROM value that was used in the SMTP transmission, which is typically stored in the Return-Path field). Note that message envelope searching is only available for the following conditions (and the corresponding exceptions):
The sender is(From)
The sender is a member of(FromMemberOf)
The sender address includes(FromAddressContainsWords)
The sender address matches(FromAddressMatchesPatterns)
The sender's domain is(SenderDomainIs)
Header or envelope ( HeaderOrEnvelope) Examine senders in the message header and the message envelope.

 Message subject or body Note
The search for words or text patterns in the subject or other header fields in the message occurs after the message has been decoded from the MIME content transfer encoding method that was used to transmit the binary message between SMTP servers in ASCII text. You can't use conditions or exceptions to search for the raw (typically, Base64) encoded values of the subject or other header fields in messages.

 This condition helps you integrate mail flow rules with SharePoint, File Classification Infrastructure (FCI) in Windows Server 2012 R2 or later, or a third-party classification system. 
 You can select from a list of built-in properties, or specify a custom property.
 Any recipients The conditions and exceptions in this section provide a unique capability that affects all recipients when the message contains at least one of the specified recipients. For example, let's say you have a rule that rejects messages. If you use a recipient condition from the Recipients section, the message is only rejected for those specified recipients. For example, if the rule finds the specified recipient in a message, but the message contains five other recipients. The message is rejected for that one recipient, and is delivered to the five other recipients.
If you add a recipient condition from this section, that same message is rejected for the detected recipient and the five other recipients. Mcneill dysphagia therapy program protocol free software.
Conversely, a recipient exception from this section prevents the rule action from being applied to all recipients of the message, not just for the detected recipients.
Note: This condition doesn't consider messages that are sent to recipient proxy addresses. It only matches messages that are sent to the recipient's primary email address.
Condition or exception in the EACCondition and exception parameters in Exchange Online PowerShellProperty typeDescription

ExceptIfAnyOfRecipientAddressMatchesPatternsPatternsMessages where the To, Cc, or Bcc fields contain text patterns that match the specified regular expressions.
 Message sensitive information types, To and Cc values, size, and character sets The conditions in this section that look for values in the To and Cc fields behave like the conditions in the Any recipients section (all recipients of the message are affected by the rule, not just the detected recipients).
Notes:
The recipient conditions in this section do not consider messages that are sent to recipient proxy addresses. They only match messages that are sent to the recipient's primary email address.
For more information about using Microsoft 365 groups with the recipient conditions in this section, see the Addresses entry in the Property types section.

ADAttributeSelect from a predefined list of Active Directory attributesYou can check against any of the following Active Directory attributes: 
City
Company
Country
CustomAttribute1 - CustomAttribute15
Department
DisplayName
Email
FaxNumber
FirstName
HomePhoneNumber
Initials
LastName
Manager
MobileNumber
Notes
Office
OtherFaxNumber

Title
UserLogonName
ZipCode
 In the EAC, to specify multiple words or text patterns for the same attribute, separate the values with commas. For example, the value San Francisco,Palo Alto for the City attribute looks for 'City equals San Francisco' or City equals Palo Alto'. 
 In Exchange Online PowerShell, use the syntax 'AttributeName1:Value1,Value 2 with spaces,Value3..','AttributeName2:Word4,Value 5 with spaces,Value6..', where Value is the word or text pattern that you want to match. For example, 'City:San Francisco,Palo Alto' or 'City:San Francisco,Palo Alto', 'Department:Sales,Finance'. 
 When you specify multiple attributes, or multiple values for the same attribute, the or operator is used. Don't use values with leading or trailing spaces. 
 Note that the Country attribute requires the two-letter ISO 3166-1 country code value (for example, DE for Germany). For more information, see Country Codes - ISO 3166.
AddressesExchange Online recipientsDepending on the nature of the condition or exception, you might be able to specify any mail-enabled object in the organization (for example, recipient-related conditions), or you might be limited to a specific object type (for example, groups for group membership conditions). And, the condition or exception might require one value, or allow multiple values. 
 In Exchange Online PowerShell, separate multiple values by commas. 
 This condition doesn't consider messages that are sent to recipient proxy addresses. It only matches messages that are sent to the recipient's primary email address. 
 The recipient picker in the EAC doesn't allow you to select Microsoft 365 groups from the list of recipients. But, you can enter the email address of a Microsoft 365 group in the box next to Check names, and then validate the email address by clicking Check names, which will add the group to the add box.
CharacterSetsArray of character set namesOne or more content character sets that exist in a message. For example: Arabic/iso-8859-6

Turkish/windows-1254
Turkish/iso-8859-9
Vietnamese/tcvn
DomainNameArray of SMTP domainsFor example, contoso.com or eu.contoso.com. 
 In Exchange Online PowerShell, you can specify multiple domains separated by commas.
EvaluatedUserSingle value of Sender or RecipientSpecifies whether the rule is looking for the manager of the sender or the manager of the recipient.
EvaluationSingle value of Equal or Not equal (NotEqual)When comparing the Active Directory attribute of the sender and recipients, this specifies whether the values should match, or not match.
ImportanceSingle value of Low, Normal, or HighThe Importance level that was assigned to the message by the sender in Outlook or Outlook on the web.
IPAddressRangesArray of IP addresses or address rangesYou enter the IPv4 addresses using the following syntax: 
• Single IP address: For example, 192.168.1.1. 
• IP address range: For example, 192.168.0.1-192.168.0.254. 
• Classless InterDomain Routing (CIDR) IP address range: For example, 192.168.0.1/25. 
 In Exchange Online PowerShell, you can specify multiple IP addresses or ranges separated by commas.
ManagementRelationshipSingle value of Manager or Direct report (DirectReport)Specifies the relationship between the sender and any of the recipients. The rule checks the Manager attribute in Active Directory to see if the sender is the manager of a recipient, or if the sender is managed by a recipient.
MessageClassificationSingle message classificationIn the EAC, you select from the list of message classifications that you've created. 
 In Exchange Online PowerShell, you use the Get-MessageClassification cmdlet to identify the message classification. For example, use the following command to search for messages with the Company Internal classification and prepend the message subject with the value CompanyInternal: New-TransportRule 'Rule Name' -HasClassification @(Get-MessageClassification 'Company Internal').Identity -PrependSubject 'CompanyInternal'
MessageHeaderFieldSingle stringSpecifies the name of the header field. The name of the header field is always paired with the value in the header field (word or text pattern match).The message header is a collection of required and optional header fields in the message. Examples of header fields are To, From, Received, and Content-Type. Official header fields are defined in RFC 5322. Unofficial header fields start with X- and are known as X-headers.
MessageTypeSingle message type valueSpecifies one of the following message types: 
• Automatic reply (OOF) 
• Auto-forward (AutoForward) 
• Encrypted
• Calendaring
• Permission controlled (PermissionControlled) 
• Voicemail
• Signed
• Approval request (ApprovalRequest) 
• Read receipt (ReadReceipt) 
Note: When Outlook or Outlook on the web is configured to forward a message, the ForwardingSmtpAddress property is added to the message. The message type isn't changed to AutoForward.
PatternsArray of regular expressionsSpecifies one or more regular expressions that are used to identify text patterns in values. For more information, see Regular Expression Syntax. 
 In Exchange Online PowerShell, you specify multiple regular expressions separated by commas, and you enclose each regular expression in quotation marks (').
SCLValueOne of the following values: 
• Bypass spam filtering (-1) 
• Integers 0 through 9Specifies the spam confidence level (SCL) that's assigned to a message. A higher SCL value indicates that a message is more likely to be spam.
SensitiveInformationTypesArray of sensitive information typesSpecifies one or more sensitive information types that are defined in your organization. For a list of built-in sensitive information types, see Sensitive information types in Exchange Server. 
 In Exchange Online PowerShell, use the syntax @{},@{},... For example, to look for content that contains at least two credit card numbers, and at least one ABA routing number, use the value @{Name='Credit Card Number'; minCount='2'},@{Name='ABA Routing Number'; minCount='1'}.
SizeSingle size valueSpecifies the size of an attachment or the whole message. 
 In the EAC, you can only specify the size in kilobytes (KB). 
 In Exchange Online PowerShell, when you enter a value, qualify the value with one of the following units: 
• B (bytes) 
• KB (kilobytes) 
• MB (megabytes)

Property type	Valid values	Description
`ADAttribute`	Select from a predefined list of Active Directory attributes	You can check against any of the following Active Directory attributes: City Company Country CustomAttribute1 - CustomAttribute15 Department DisplayName Email FaxNumber FirstName HomePhoneNumber Initials LastName Manager MobileNumber Notes Office OtherFaxNumber OtherHomePhoneNumber OtherPhoneNumber PagerNumber PhoneNumber POBox State Street Title UserLogonName ZipCode In the EAC, to specify multiple words or text patterns for the same attribute, separate the values with commas. For example, the value `San Francisco,Palo Alto` for the City attribute looks for 'City equals San Francisco' or City equals Palo Alto'. In Exchange Online PowerShell, use the syntax `'AttributeName1:Value1,Value 2 with spaces,Value3..','AttributeName2:Word4,Value 5 with spaces,Value6..'`, where `Value` is the word or text pattern that you want to match. For example, `'City:San Francisco,Palo Alto'` or `'City:San Francisco,Palo Alto'`, `'Department:Sales,Finance'`. When you specify multiple attributes, or multiple values for the same attribute, the or operator is used. Don't use values with leading or trailing spaces. Note that the Country attribute requires the two-letter ISO 3166-1 country code value (for example, DE for Germany). For more information, see Country Codes - ISO 3166.
`Addresses`	Exchange Online recipients	Depending on the nature of the condition or exception, you might be able to specify any mail-enabled object in the organization (for example, recipient-related conditions), or you might be limited to a specific object type (for example, groups for group membership conditions). And, the condition or exception might require one value, or allow multiple values. In Exchange Online PowerShell, separate multiple values by commas. This condition doesn't consider messages that are sent to recipient proxy addresses. It only matches messages that are sent to the recipient's primary email address. The recipient picker in the EAC doesn't allow you to select Microsoft 365 groups from the list of recipients. But, you can enter the email address of a Microsoft 365 group in the box next to Check names, and then validate the email address by clicking Check names, which will add the group to the add box.
`CharacterSets`	Array of character set names	One or more content character sets that exist in a message.

`DomainName`	Array of SMTP domains	For example, `contoso.com` or `eu.contoso.com`. In Exchange Online PowerShell, you can specify multiple domains separated by commas.
`EvaluatedUser`	Single value of Sender or Recipient	Specifies whether the rule is looking for the manager of the sender or the manager of the recipient.
`Evaluation`	Single value of Equal or Not equal (`NotEqual`)	When comparing the Active Directory attribute of the sender and recipients, this specifies whether the values should match, or not match.
`Importance`	Single value of Low, Normal, or High	The Importance level that was assigned to the message by the sender in Outlook or Outlook on the web.
`IPAddressRanges`	Array of IP addresses or address ranges	You enter the IPv4 addresses using the following syntax: • Single IP address: For example, `192.168.1.1`. • IP address range: For example, `192.168.0.1-192.168.0.254`. • Classless InterDomain Routing (CIDR) IP address range: For example, `192.168.0.1/25`. In Exchange Online PowerShell, you can specify multiple IP addresses or ranges separated by commas.
`ManagementRelationship`	Single value of Manager or Direct report (`DirectReport`)	Specifies the relationship between the sender and any of the recipients. The rule checks the Manager attribute in Active Directory to see if the sender is the manager of a recipient, or if the sender is managed by a recipient.
`MessageClassification`	Single message classification	In the EAC, you select from the list of message classifications that you've created. In Exchange Online PowerShell, you use the Get-MessageClassification cmdlet to identify the message classification. For example, use the following command to search for messages with the `Company Internal` classification and prepend the message subject with the value `CompanyInternal`: `New-TransportRule 'Rule Name' -HasClassification @(Get-MessageClassification 'Company Internal').Identity -PrependSubject 'CompanyInternal'`
`MessageHeaderField`	Single string	Specifies the name of the header field. The name of the header field is always paired with the value in the header field (word or text pattern match).The message header is a collection of required and optional header fields in the message. Examples of header fields are To, From, Received, and Content-Type. Official header fields are defined in RFC 5322. Unofficial header fields start with X- and are known as X-headers.
`MessageType`	Single message type value	Specifies one of the following message types: • Automatic reply (`OOF`) • Auto-forward (`AutoForward`) • Encrypted • Calendaring • Permission controlled (`PermissionControlled`) • Voicemail • Signed • Approval request (`ApprovalRequest`) • Read receipt (`ReadReceipt`) Note: When Outlook or Outlook on the web is configured to forward a message, the ForwardingSmtpAddress property is added to the message. The message type isn't changed to `AutoForward`.
`Patterns`	Array of regular expressions	Specifies one or more regular expressions that are used to identify text patterns in values. For more information, see Regular Expression Syntax. In Exchange Online PowerShell, you specify multiple regular expressions separated by commas, and you enclose each regular expression in quotation marks (').
`SCLValue`	One of the following values: • Bypass spam filtering (`-1`) • Integers 0 through 9	Specifies the spam confidence level (SCL) that's assigned to a message. A higher SCL value indicates that a message is more likely to be spam.
`SensitiveInformationTypes`	Array of sensitive information types	Specifies one or more sensitive information types that are defined in your organization. For a list of built-in sensitive information types, see Sensitive information types in Exchange Server. In Exchange Online PowerShell, use the syntax `@{},@{},..`. For example, to look for content that contains at least two credit card numbers, and at least one ABA routing number, use the value `@{Name='Credit Card Number'; minCount='2'},@{Name='ABA Routing Number'; minCount='1'}`.
`Size`	Single size value	Specifies the size of an attachment or the whole message. In the EAC, you can only specify the size in kilobytes (KB). In Exchange Online PowerShell, when you enter a value, qualify the value with one of the following units: • `B` (bytes) • `KB` (kilobytes) • `MB` (megabytes) • `GB` (gigabytes) For example, `20 MB`. Unqualified values are typically treated as bytes, but small values may be rounded up to the nearest kilobyte.
`SupervisionList`	Single value of Allow or Block	Supervision policies were a feature in Live@edu that allowed you to control who could send mail to and receive mail from users in your organization (for example, the closed campus and anti-bullying policies). In Microsoft 365 and Office 365, you can't configure supervision list entries on mailboxes.
`UserScopeFrom`	Single value of Inside the organization (`InOrganization`) or Outside the organization (`NotInOrganization`)	A sender is considered to be inside the organization if either of the following conditions is true: • The sender is a mailbox, mail user, group, or mail-enabled public folder that exists inside the organization. • The sender's email address is in an accepted domain that's configured as an authoritative domain or an internal relay domain, and the message was sent or received over an authenticated connection. For more information about accepted domains, see Manage accepted domains in Exchange Online. A sender is considered to be outside the organization if either of the following conditions is true: • The sender's email address isn't in an accepted domain. • The sender's email address is in an accepted domain that's configured as an external relay domain. Note: To determine whether mail contacts are considered to be inside or outside the organization, the sender's address is compared with the organization's accepted domains.
`UserScopeTo`	One of the following values: • Inside the organization (`InOrganization`) • Outside the organization (`NotInOrganization`)	A recipient is considered to be inside the organization if either of the following conditions is true: • The recipient is a mailbox, mail user, group, or mail-enabled public folder that exists inside the organization. • The recipient's email address is in an accepted domain that's configured as an authoritative domain or an internal relay domain, and the message was sent or received over an authenticated connection. A recipient is considered to be outside the organization if either of the following conditions is true: • The recipient's email address isn't in an accepted domain. • The recipient's email address is in an accepted domain that's configured as an external relay domain.
`Words`	Array of strings	Specifies one or more words to look for. The words aren't case-sensitive, and can be surrounded by spaces and punctuation marks. Wildcards and partial matches aren't supported. For example, 'contoso' matches ' Contoso'. However, if the text is surrounded by other characters, it isn't considered a match. For example, 'contoso' doesn't match the following values: • Acontoso • Contosoa • Acontosob The asterisk (*) is treated as a literal character, and isn't used as a wildcard character.
