When you see Object IDs instead of names in a Dynamic Distribution List, it usually means that the system is displaying the unique identifier for each member rather than their actual names. This can happen for a few reasons:

Possible Causes:

Directory Sync Issues: There might be a problem with synchronization between Azure Active Directory (AAD) and your Exchange Online environment. If the sync isn't happening properly, the system might display Object IDs instead of names.

Permissions or Access Issues: If the account used to view the list doesn’t have the proper permissions, it might not be able to resolve the names and will display Object IDs instead.

Corrupt or Incomplete Data: The data might be incomplete or corrupted in some way, leading the system to show Object IDs.

How to Fix It:

Check Synchronization: Ensure that directory synchronization is working correctly between Azure Active Directory and Exchange. You might need to force a manual sync.

Verify Permissions: Ensure that the account you are using has the necessary permissions to view the list. This includes having the right roles assigned in Azure AD and Exchange.

Refresh the List: Sometimes simply refreshing or reloading the list can resolve the issue. If the list is dynamic, it might take a moment for the system to properly resolve all names.

Contact Support: If the issue persists, you might need to contact Microsoft support for further assistance, as it could be an underlying issue with the system.

In simpler terms, the system is showing the ID numbers instead of names because it can’t properly match them. By checking the sync process, permissions, and refreshing the list, you can usually get the names to display correctly again.When you see Object IDs instead of names in a Dynamic Distribution List, it usually means that the system is displaying the unique identifier for each member rather than their actual names.

There's nothing to correct here, Microsoft recently changed the way how recipients are displayed in various admin interfaces. You can read about the changes here: https://techcommunity.microsoft.com/t5/exchange-team-blog/change-in-naming-convention-of-user-s-name-parameter/ba-p/3284733

As long as the right set of users are showing up in the list, you can ignore this - it's purely cosmetical.

You can still search for the user by name or any other identifier, or "resolve" the GUID you see therein in other parts of the portal of via PowerShell (Get-Recipient GUID).

Reading the EDOID is way more difficult than someone's name.
