Method #1

Follow the below steps to fix the issue regarding Mac Outlook 2011 not syncing with the Exchange Server:

  1. Firstly, you need to end all the Microsoft Office related processes.
  2. After that, create a replica or backup of Office 2011 identities folder, which is present in “~/Documents/Microsoft User Data/Office 2011 identities/”
  3. Next, click on the Alt key while you click on Outlook to open it.
  4. This will directly go into the Microsoft database utility mode, where you can recreate an identity.
  5. Now, select the identity that is required. Then, click on the Rebuild option. It will take some time.

If in case, only one folder is not syncing, but others are synced properly. Then you can attempt Empty the Cache option. That means you can re-sync the folder with the Exchange Server by following the given below steps:
