It may be an issue with your database.

One option to try is to start eM Client with a new blank database, and see if the issue is still there. To do that first make a backup of eM Client (Menu > File > Backup) then close eM Client and delete the  *C:\Users* _ yourusername _ \AppData\Roaming\eM Client  folder. You may need to enable hidden items in Windows Explorer to get there.

When you restart eM Client, you will have an empty database. Setup your accounts and see what happens.

If that does not make any difference you can restore your old database (Menu > File > Restore) or just keep the current one.
