A group naming policy lets you standardize and manage the names of distribution groups created by users in your organization. You can require a specific prefix and suffix be added to the name for a distribution group when it's created, and you can block specific words from being used. This helps you minimize the use of inappropriate words in group names.

A group naming policy:

How does a group naming policy work? When a user creates a group, they specify a name in the Display Name field. After the group is created, Microsoft Exchange applies the group naming policy by adding any prefix or suffix that you've defined in the group naming policy. The full name is displayed in the distribution groups list in the Exchange Administration Center (EAC), the shared address book, and the To:, Cc:, and From: fields in email messages. If a user tries to use a word that you've blocked, they get an error message when they try to save the new group and are asked to remove the blocked word and save the group again.

Here are some examples of a group naming policy. In each, <Group Name> is a descriptive name provided by the person who creates the group. Exchange adds the prefixes and suffixes defined by the policy to the display name when the group is created.

What do you need to know before you begin?

  • Estimated time to complete: 5 minutes.

  • You need to be assigned permissions before you can perform this procedure or procedures. To see what permissions you need, see the "Distribution Groups" entry in the Recipients Permissions topic.

  • The maximum length for a group name is 64 characters. This includes the combined number of characters in the prefix, the group name provided by the user, and the suffix.

  • The group naming policy is applied only to groups created by users. When you or other administrators use the EAC to create distribution groups, the group naming policy is ignored and not applied to the group name.

  • Group names are created without spacing. We recommend that you use an underscore character (_) or some other placeholder between text strings, attributes, and the group name.

  • You can use Windows PowerShell to override the group naming policy when you create and edit a distribution group. For more information, see Override the Distribution Group Naming Policy.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard Shortcuts in the Exchange Admin Center.
