Connection Fail

It only does this when I try going to other folders when I open eM Client. But when I do a Diagnostics test, everything is fine.

Imap. An attempt to connect to [email protected] failed. 7:29:19 AM [email protected] [IMAP] MailExceptions.ConnectionException: Cannot open folder “{0}”. 7:29:19 AM (Connection terminated)

Hi Chuck, seems like a synchronizing error.
Try Right mouse-clicking on your account in the left side menu and choose Properties>Repair. Click repair and wait for the account to resync and see if the issue persists.

Regards,
