Hi FCH-M365,
Thank you for posting in the Q&A Forums.
First, confirm that the synchronization between Active Directory and Microsoft Entra (possibly referring to Azure Active Directory or other Microsoft cloud services) is set up correctly and is working.
If you're using Azure AD Connect or another sync tool, check its configuration and sync status to make sure there are no errors or delays.
In Azure AD Connect or other sync tools, there may be specific sync rules that may have affected the user's deactivated status.
If you notice a delay in syncing, you can try manually triggering a sync to ensure that the changes take effect immediately.
You can audit user account changes in Active Directory to ensure that the changes have been applied correctly.
This can also help you determine if the changes were successfully synced to Microsoft Entra.
Check Active Directory and Microsoft Entra's logs and events for details about synchronization and user state changes.
Best regards
NeuviJ
