Sync issues folder in outlook suddenly appeared

Question

all of a sudden my outlook folders are showing a sync issues folder. How do I get rid of the folder in outlook?

Answer 1

I would suggest that instead of deleting the Sync Issues folders, you check them for errors and then just clear the contents. They can contain valuable information if you are having sync problems.

If you still want to get rid of them - You should be able to do a simple folder Delete. But it may come back if there is a sync error. You can try hiding them instead.

Answer 2

The Sync Issues folder is a built‑in client-side folder in Outlook and cannot be removed or deleted. It is used to store synchronization logs and error messages when Outlook has trouble syncing with the server or an IMAP account.

The folder itself will remain in the folder list, but its contents can be ignored or cleared if not needed. If many items accumulate there, AutoArchive can be used to automatically empty it. However, the folder will still appear in Outlook.
