Sync Issues

[Ben Killoy]

I have an end user who is on Outlook 2016 with on-premise exchange and we here inbox only updates when I click "Update Folder" in send/receive ribbon.  

I tried cleaining the local cache on the inbox folder and let it rebuild as I found one article saying that this was a known issue.  

But the issue came back once it was fully synced again.  

I am stuck and what tricks to use to help troubleshoot, I hate rebuilding profiles as they are big distruption to the users day while their mailbox is downloading.  

Any ideas

Try running Outlook in Safe mode or recreating the profile. How big is the OST?

7GB's so I try to hold the profile restore as a last resort

I haven't tried safe mode I will try that real quick

Putting it into safe mode actually made it stop working and even without safe mode it wasn't connecting.

I did check at the file location of and notice our Carbonite was grabbing this file to back up and I think this was causing conflict on the sync.

Once I stopped syncing it from carbonite it came back.

It sounds to me that it's switched to work offline mode. Go through the tabs (I'm not in front of a pc) and check that work offline is not enabled
