The group naming policy for distribution groups is applied only to groups created by users. When you or other administrators use the Exchange Administration Center (EAC) to create distribution groups, the group naming policy is ignored and not applied to the group name.
However, if you use the Exchange Management Shell to create or rename a distribution group, the group naming policy is applied to groups created by administrators unless you use the IgnoreNamingPolicy parameter to override the group naming policy.

What do you want to do?
Use the Shell to override the group naming policy when you create a new group
To override the group naming policy, run the following command.
 Copy Code |
|
|---|---|
New-DistributionGroup -Name <Group Name> -IgnoreNamingPolicy |
|
For example, if the group naming policy for your organization is DG_<Group Name>_Users, run the following command to create a group named All Administrators.
| Copy Code |
|
|---|---|
New-DistributionGroup -Name "All Administrators" -IgnoreNamingPolicy |
|
When Microsoft Exchange creates this group, it uses All Administrators for both the Name and DisplayName parameters.
Use the Shell to override the group naming policy when you rename a group
To override the group naming policy when you rename an existing group with the Shell, run the following command.
| Copy Code |
|
|---|---|
Set-DistributionGroup -Identity <Old Group Name> -Name <New Group Name> -DisplayName <New Group Name> -IgnoreNamingPolicy |
|
For example, let's say you created a group naming policy late one night and the next morning you realized you misspelled the text string in the prefix. The next morning, you see that a new group has already been created with the misspelled prefix. You can fix the group naming policy in the EAC, but you have to use the Shell to rename the group with the misspelled name. Run the following command.
| Copy Code |
|
|---|---|
Set-DistributionGroup -Identity "Goverment_Contracts_NWRegion" -Name "Government_ContractEstimates_NWRegion" -DisplayName "Government_ContractEstimates_NWRegion" -IgnoreNamingPolicy |
|
 Important: |
|---|
| Be sure to include the DisplayName parameter when you rename a group. If you don't, the old name is still displayed in the shared address book on the To:, Cc:, and From: lines in email messages. |
How do you know this worked?
To verify that you’ve successfully created or renamed a distribution group that ignores the group naming policy, run the following commands.
| Copy Code |
|
|---|---|
Get-DistributionGroup <Name> | FL DisplayName |
|
| Copy Code |
|
|---|---|
Get-OrganizationConfig | FL DistributionGroupNamingPolicy |
|
If the format of the display name for the group is different than the one enforced by your organization’s group naming policy, it worked.
