What should I do if my sync failed due to authentication issues?
You can run a sync manually with PowerShell or the Azure AD Connect tool to make sure updates go through. Checking the sync logs helps confirm password changes are making it everywhere they should. The Repair Outlook Profile Online idea is to provide a recycle bin of users who you can delete when you no longer need them. You can view your inactive users on the Users page and delete them as you see fit.
On the sync server, we open the Synchronization Service Manager and check that the last sync finished without errors. Azure AD Connect handles password sync, but it runs on a schedule—usually every 30 minutes. So, if you just changed your password, there might be a short window where your old password still works and the new one hasn’t reached every system.
The sync will fail if it can't find any users that comply with your filtering preferences or the system's requirements for user records. The system requires that users have a first name, last name and a valid email address that conforms with your domain lock if enabled.

Keeping Azure AD Connect up to Office 365 sync problems and login fixes date and testing sync regularly helps password resets flow like they’re supposed to. Password sync usually fails when credentials don’t update between Microsoft Entra ID (Azure AD) and your on-premises Active Directory. Most of the time, the problem comes from timing delays, configuration mistakes, or cached credentials on devices that don’t pick up new passwords. Outdated credentials get stuck on devices, password sync gets turned off, or Microsoft Entra Connect just doesn’t update like it should. Here’s a step-by-step approach to help you spot the issue, fix it, and avoid these sync delays down the road.
