Filterable properties for the Filter parameter on Exchange cmdlets

Article
01/09/2024

You use the Filter parameter to create OPATH filters based on the properties of user and group objects in the Exchange Management Shell (Exchange Server PowerShell) and in Exchange Online PowerShell. The Filter parameter is available on these recipient cmdlets:

For more information about recipient filters in Exchange PowerShell, see Recipient filters in Exchange PowerShell commands.

Note

The Filter parameter is also available on other cmdlets (for example, Get-MailboxStatistics, Get-Queue, and Get-Message). However, the property values that are accepted by the Filter parameter on these cmdlets aren't similar to the user and group properties that are described in this article.

The properties that have been confirmed to work with the Filter parameter in user and group cmdlets are described in this article.

Notes:

The list might include:
- Properties that are used only in one type of environment: Microsoft 365, on-premises Exchange, or hybrid. The property might exist on recipient objects in all environments, but the value is meaningful (a value other than blank or None) only in one type of environment.
- Properties that are present, but correspond to features that are no longer used.
Not all recipient properties have a corresponding Active Directory property. The LDAP display name value is "n/a" for these properties, which indicates that the property is calculated (likely by Exchange).
Enclose the whole OPATH filter in double quotation marks " ". If the filter contains system values (for example, $true, $false, or $null), use single quotation marks ' ' instead. Although the Filter parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables. For more information, see Additional OPATH syntax information.
Text string properties that accept wildcard characters require the -like operator (for example, "Property -like 'abc*'").
To look for blank or non-blank property values, use the value $null (for example, 'Property -eq $null' or 'Property -ne $null').
For filtering considerations for the nine exclusive Get-EXO* cmdlets in the Exchange Online PowerShell module, see Filters in the Exchange Online PowerShell module.

AcceptMessagesOnlyFrom

LDAP display name	Available on cmdlets	Value
authOrig	Get-DistributionGroup Get-DynamicDistributionGroup Get-Mailbox Get-MailContact Get-MailPublicFolder Get-MailUser Get-RemoteMailbox Get-UnifiedGroup	String or `$null`

This filter requires the distinguished name of the individual recipient (a mailbox, mail user, or mail contact). For example, Get-DistributionGroup -Filter "AcceptMessagesOnlyFrom -eq 'CN=Yuudai Uchida,CN=Users,DC=contoso,DC=com'" or Get-DistributionGroup -Filter "AcceptMessagesOnlyFrom -eq 'contoso.com/Users/Angela Gruber'".

To find the distinguished name of the individual recipient, replace <RecipientIdentity> with the name, alias, or email address of the recipient, and run this command: Get-Recipient -Identity "<RecipientIdentity>" | Format-List Name,DistinguishedName.

Although this property is multi-valued, the filter returns a match if the property contains the specified value.

Note that an object's Exchange GUID value is different than its GUID value. Also, the Exchange GUID value for non-mailboxes (mail contacts, mail users, distribution groups, dynamic distribution groups, mail-enabled security groups, and mail-enabled public folders) is 00000000-0000-0000-0000-000000000000.
