Outlook 2016 hangs on updating inbox
Now when Outlook is open, theres a message in the status bar "waiting to update this folder".It would just wait there for maybe 15 minutes then any new emails waiting would come in. Strange thing is, it only happens when the inbox is selected. If you see a lot of Conflicts or Failures this is the case.
Extracted and imported all mailboxes for users and everything works fine... The import of the old mailbox completed and synced with exchange.
1] Run Microsoft Outlook in Safe Mode, without add-ins.
To do this, open Run box from the Win X Menu, type and hit Enter.
One thing you want to know is that when you disable Hardware Acceleration for Outlook, it gets turned off for all Office programs.
3] At the time, your Outlook may be busy carrying out some other processes, like synchronizing your email, archiving old items, etc. In such situations, it’s best to let Outlook complete its task.
