How do I fix this?
Using Classic Outlook on Windows for personal email, calendar, and contact management
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
unfortunately the problem is still not fixed. after a couple of messages it´s again broken.
items created in the meantime seem not to sync, so it might be necessary to remove/readd the required folders to the favorites
updated outlook to version 14827.20192
according to some first tests it seems to be fixed, even though the sync error messages still appear.
will test further and share the results.
anyone can already confirm or refute ?
Hi Maxpayne0815
Microsoft has fixed it
Pls test and let me know
sounds promising, thanks for sharing !
but I assume you haven´t been told an implementation date ?
