Office 365 DirSync stopped-server-down

admin

I could not find a new AD user in Office 365. I went to the DirSync server to force a synchronization by opening powershell and navigated to the folder:

C:\Program Files\Microsoft Online Directory Sync.

Then start the Directory Sync Configuration Shell by typing:
.\DirSyncConfigShell.psc1powershell-dirsync

That launched the Dir Sync powershell window.  Once opened I typed:

Start-OnlineCoexistenceSync
start-onlinecoexistencesync

 

After this point I still was missing the user, so I launched the Synchronization Service Manager:

C:\Program Files\Microsoft Online Directory Sync\SYNCBUS\Synchronization Service\UIShell

server-down

From here I noticed all the “stopped-server-down” messages on the TargetWebService line.

After some digging I noticed that the service account password had changed the same day DirSync stopped working.  To update the service account password from within the Synchronization Service Manager go to

Management Agents > right click TargetWebService, hit properties…

management agents

Then go to Configure Connection Information. Update the user and password in the connection information box.

After this, repeat the steps to do a DirSync from above, and everything should be back to normal.
