Description
A dynamic distribution group queries mail-enabled objects and builds the group membership based on the results. The group membership is recalculated whenever an email message is sent to the group.
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Get-DynamicDistributionGroup
This example returns a summary list of all dynamic distribution groups in your organization.
Example 2
Get-DynamicDistributionGroup -Identity "Marketing Department" | Format-List
This example returns detailed information about the dynamic distribution group named Marketing Department.
Example 3
Get-DynamicDistributionGroup -Anr *research* | Format-Table Name, ManagedBy -Auto
This example returns all dynamic distribution groups whose names contain the string "research" and shows the group owners.
Example 4
$FTE = Get-DynamicDistributionGroup "Full Time Employees"
Get-Recipient -RecipientPreviewFilter $FTE.RecipientFilter -OrganizationalUnit $FTE.RecipientContainer
This example returns the members for the dynamic distribution group named Full Time Employees. The first command stores the dynamic distribution group object in the variable $FTE. The second command uses the Get-Recipient cmdlet to list the recipients that match the criteria defined for the dynamic distribution group.
Parameters
-Anr
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
The Anr parameter specifies a string on which to perform an ambiguous name resolution (ANR) search. You can specify a partial string and search for objects with an attribute that matches that string. The default attributes searched are:
- CommonName (CN)
- DisplayName
- FirstName
- LastName
- Alias
Parameter properties

Parameter sets
AnrSet

| Value from remaining arguments: | False |
-Credential
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
The Credential parameter specifies the username and password that's used to run this command. Typically, you use this parameter in scripts or when you need to provide different credentials that have the required permissions.
A value for this parameter requires the Get-Credential cmdlet. To pause this command and receive a prompt for credentials, use the value (Get-Credential). Or, before you run this command, store the credentials in a variable (for example, $cred = Get-Credential) and then use the variable name ($cred) for this parameter. For more information, see Get-Credential.

-DomainController
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
This parameter is available only in on-premises Exchange.
The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

-Filter
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
The Filter parameter uses OPATH syntax to filter the results by the specified properties and values. The search criteria uses the syntax "Property -ComparisonOperator 'Value'".
- Enclose the whole OPATH filter in double quotation marks " ". If the filter contains system values (for example,
$true,$false, or$null), use single quotation marks ' ' instead. Although this parameter is a string (not a system block), you can also use braces { }, but only if the filter doesn't contain variables. - Property is a filterable property. For more information about the filterable properties, see Filterable properties for the Filter parameter.
- ComparisonOperator is an OPATH comparison operator (for example
-eqfor equals and-likefor string comparison). For more information about comparison operators, see about_Comparison_Operators. - Value is the property value to search for. Enclose text values and variables in single quotation marks (
'Value'or'$Variable'). If a variable value contains single quotation marks, you need to identify (escape) the single quotation marks to expand the variable correctly. For example, instead of'$User', use'$($User -Replace "'","''")'. Don't enclose integers or system values in quotation marks (for example, use500,$true,$false, or$nullinstead).
You can chain multiple search criteria together using the logical operators -and and -or. For example, "Criteria1 -and Criteria2" or "(Criteria1 -and Criteria2) -or Criteria3".
For detailed information about OPATH filters in Exchange, see Additional OPATH syntax information.

-IgnoreDefaultScope
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
This parameter is available only in on-premises Exchange.
The IgnoreDefaultScope switch tells the command to ignore the default recipient scope setting for the Exchange PowerShell session, and to use the entire forest as the scope. You don't need to specify a value with this switch.
This switch enables the command to access Active Directory objects that aren't currently available in the default scope, but also introduces the following restrictions:
- You can't use the DomainController parameter. The command uses an appropriate global catalog server automatically.
- You can only use the DN for the Identity parameter. Other forms of identification, such as alias or GUID, aren't accepted.
