Problems with "Sync-Vorgänge" - Sync with Exchange Server

Sync with Exchange doesn’t work properly. I always get error below.
I am using a Test Version at the moment. please help me…

There are seldom solutions to Exchange issues on this forum. I think that may be because Exchange is generally used in business environments, and those users have access to eM Client VIP Support, so they are not reporting issue here.

All I can suggest is to remove the account from eM Client, then add it again and make sure you are using the correct credentials.
