Outlook mails not synchronising

Since a week, I get error messages when synchronising Outlook.

Can someone please explain how to solve this issue? Until a few days, everything was fine and now my mails won’t synchronise any more.

Many thanks and greetings,

Michel

Michel,

Have you checked the mapping of the IMAP folders in your account settings? Maybe something is wrong there?
