How to Change a Dynamic Microsoft 365 Group Display Name
Question details
The user needs to change the display name of a dynamic Microsoft 365 group with minimal impact to the production environment.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Updating group naming conventions (e.g., from ALLUWSTAFF to ALLSTAFF) without disrupting existing email addresses or dynamic membership rules.
- Observed behavior
- The administrator intends to update the group's display name and needs to ensure the change is properly reflected in the Global Address List (GAL).
Before making changes, confirm that the dynamic group is not actively referenced by its specific display name in administrative scripts, mail-flow rules, or third-party applications.
Change Group Name via Microsoft 365 Exchange Admin Center
The safest and most direct method to update a group's display name without altering its backend rules or email address.
Using the Exchange admin center allows you to modify the display properties of a dynamic group seamlessly. This ensures that users see the updated name in their address books while maintaining the integrity of the underlying system configurations.
Log in to the Microsoft 365 admin center, locate the admin centers menu on the left sidebar, and open the Exchange admin center.
In the Exchange admin center dashboard, go to the 'Recipients' section and click on 'Groups'.
Select 'Microsoft 365' or the specific dynamic group category, and find the group you want to modify from the list.
Click on the group to open its properties pane. Choose the option to 'Edit name and description', enter the new display name, and click save.
After saving the changes, open the Global Address List (GAL) in Outlook or Exchange to verify that the new display name is correctly populated.

Frequently Asked Questions
Will changing the group display name also change its email address?
No, updating the display name in the Microsoft 365 or Exchange admin center only alters how the group appears in the address book. The primary email address and aliases remain unchanged unless manually modified.
How long does it take for the new group name to appear in the Global Address List (GAL)?
Changes made in the Exchange admin center typically sync with the GAL within a few minutes, though it can sometimes take up to 24 hours to fully propagate to all users' offline address books (OAB).
Does renaming a dynamic group affect its membership rules?
Renaming the group's display name has no impact on its dynamic membership rules. The attributes and queries used to determine who belongs to the group will continue to function exactly as they did before the name change.
