If a password reset in Office 365 isn’t syncing, users usually get sign-in errors or find old credentials still hanging around on devices. We focus on restoring sync between Microsoft Entra ID (Azure AD), on-premises Active Directory, and user devices so everyone gets back in without headaches. If password sync is off or the server is in staging mode, passwords won’t update. We turn password sync back on by running the Entra Connect configuration wizard and picking Customize synchronization options. Check that your password change actually synced between your on-premises Active Directory and Microsoft Entra ID (formerly Azure AD). If it didn’t, a few targeted checks usually restore access—no need to keep resetting your password over and over.

What to do when Office 365 password reset doesn’t sync across devices

I have multiple users experiencing sync errors with Outlook and office365. Another which is shown below, is a user opens a new message, or replies to one, and lets it sit for a while. When they go back to the message and press send they get an error that the message has been deleted. Ive repaired the OST and changed cache mode to only cache 1 year.

With apps syncing across devices and cloud services, sync issues are among the most frequently reported M365 problems. These can include missing files, ghost icons, or documents that do not update in real-time. The sync will fail if the total number of all users (active or inactive) on your account exceeds the user limit placed upon it if present.

Reviewing Device Sign-In Settings

You can view your Office 365 Sync Errors Fix inactive users on the Users page and delete them as you see fit. Similarly you should review the Users Deactivated sheet on the sync summary spreadsheet attachment as you can also delete these users to bring your total down. If sync keeps failing, we make sure the Microsoft Entra Connect service account has the right permissions and the server connects to the domain controller. Updating Azure AD Connect to the latest build often fixes known sync issues.

Common Causes of Office 365 Password Reset Sync Issues

• If problems stick around, we rejoin the devices to Microsoft 365 services.
• Even I've only been doing this with test users so far, so haven't actually broken any actual users yet, I still need to get this resolved quickly.
• We also scan Event Viewer logs under Applications and Services Logs → Directory Synchronization for Event IDs like 650–657 (for sync activity).
• We also check the synchronization scheduler to confirm delta and full sync cycles finish successfully.
• The system requires that users have a first name, last name and a valid email address that conforms with your domain lock if enabled.
• You can stop any accounts from being brought over by adding them to the sync deny list.
• Users I create within the Office 365 portal are fine, so I assume it is something to do with Azure AD Connect.
