How to re-create an Outlook Profile using the desktop app for Windows

Follow these steps to re-create your Outlook Profile

  9. Click OK to proceed.

  10. Now launch Outlook. Allow time for the new profile to synchronise with Exchange Server. This process can take 20-30mins if your mailbox is large. Connection speed will need to be considered as well.

  11. After the mailbox synchronisation completes, try closing and re-opening Outlook. If everything is working ok with the new profile then you can safely remove the original profile:
