Description

The Get-Group cmdlet returns no mail-related properties for distribution groups or mail-enabled security groups, and no role group-related properties for role groups. To view the object-specific properties for a group, you need to use the corresponding cmdlet based on the object type (for example, Get-DistributionGroup or Get-RoleGroup).

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not 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 (https://technet.microsoft.com/library/mt432940.aspx).

Optional Parameters

-AccountPartition

This parameter is reserved for internal Microsoft use.

Type:AccountPartitionIdParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-Anr

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

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-Credential

The Credential parameter specifies the user name 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.

This parameter requires the creation and passing of a credential object. This credential object is created by using the Get-Credential cmdlet. For more information, see Get-Credential (https://go.microsoft.com/fwlink/p/?linkId=142122).

Type:PSCredential
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-DomainController

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.

The DomainController parameter isn't supported on Edge Transport servers. An Edge Transport server uses the local instance of Active Directory Lightweight Directory Services (AD LDS) to read and write data.

Type:Fqdn
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-Filter

The Filter parameter uses OPATH filter syntax to filter the results by the specified properties and values. The search criteria uses the syntax {<Property> -<Comparison operator> '<Value>'}.

  • <Property> is a filterable property.

  • -<Comparison Operator> is an OPATH comparison operator. For example -eq for equals and -like for string comparison. For more information about comparison operators, see about_Comparison_Operators (https://go.microsoft.com/fwlink/p/?LinkId=620712).

  • <Value> is the property value. Text values with or without spaces need to be enclosed in quotation marks ('<Value>'). Don't use quotation marks with integers or the system values $true, $false, or $null.

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>}.

You can filter by the following properties:

  • AdministrativeUnits

  • DisplayName

  • DistinguishedName

  • ExchangeVersion

  • GroupType

  • Guid

  • Id

  • IsDirSynced

  • ManagedBy

  • Name

  • Notes

  • ObjectCategory

  • ObjectClass

  • PhoneticDisplayName

  • RecipientType

  • RecipientTypeDetails

  • SamAccountName

  • Sid

  • SidHistory

  • SimpleDisplayName

  • WhenChanged

  • WhenChangedUTC

  • WhenCreated

  • WhenCreatedUTC

  • WindowsEmailAddress

For more information, see Filterable properties for the -Filter parameter (https://technet.microsoft.com/library/bb738155.aspx).

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-Identity

The Identity parameter specifies the group object that you want to view. You can use any value that uniquely identifies the group.

For example:

  • Name

  • Display name

  • Distinguished name (DN)

  • Canonical DN

  • GUID

Type:GroupIdParameter
Position:1
Default value:None
Accept pipeline input:True
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-IgnoreDefaultScope

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 Management Shell session, and to use the entire forest as the scope. This allows the command to access Active Directory objects that aren't currently available in the default scope.

Using the IgnoreDefaultScope switch 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.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-OrganizationalUnit

The OrganizationalUnit parameter filters the results based on the object's location in Active Directory. Only objects that exist in the specified location are returned. Valid input for this parameter is an organizational unit (OU) or domain that's visible using the Get-OrganizationalUnit cmdlet. You can use any value that uniquely identifies the OU or domain. For example:

  • Name

  • Canonical name

  • Distinguished name (DN)

  • GUID

Type:OrganizationalUnitIdParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-ReadFromDomainController

This parameter is available only in on-premises Exchange.

The ReadFromDomainController switch specifies that information should be read from a domain controller in the user's domain. If you run the command Set-AdServerSettings -ViewEntireForest $true to include all objects in the forest and you don't use the ReadFromDomainController switch, it's possible that information will be read from a global catalog that has outdated information. When you use the ReadFromDomainController switch, multiple reads might be necessary to get the information. You don't have to specify a value with this switch.

By default, the recipient scope is set to the domain that hosts your Exchange servers.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-RecipientTypeDetails

The RecipientTypeDetails parameter filters the results by the specified group subtype. Valid values are:

  • MailNonUniversalGroup

  • MailUniversalDistributionGroup

  • MailUniversalSecurityGroup

  • RoomList

You can specify multiple values separated by commas.

Type:RecipientTypeDetails[]
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-ResultSize

The ResultSize parameter specifies the maximum number of results to return. If you want to return all requests that match the query, use unlimited for the value of this parameter. The default value is 1000.

Type:Unlimited
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
-SortBy

The SortBy parameter specifies the property to sort the results by. You can sort by only one property at a time. The results are sorted in ascending order.

If the default view doesn't include the property you're sorting by, you can append the command with | Format-Table -Auto <Property1>,<Property2>... to create a new view that contains all of the properties that you want to see. Wildcards (*) in the property names are supported.

You can sort by the following properties:

  • Name

  • DisplayName

Type:String
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Online Protection
