BAD User is authenticated but not connected

Reported by vramdal (at gmail) | December 8th, 2016 @ 11:22 AM

When MailMate is synching my folders on Outlook 365, it produces a number of these error messages:

MailMate encountered the following error: “Server response: “D5 BAD User is authenticated but not connected.”.”.
Mailbox: “(Custom Expiration\Manage Folders)”.

Clicking Retry or Try later only postpones the problem.

The folder it has problems with is different from time to time. The sync does not fail completely: I usually get to see at least some new mail in my inbox. However, the error occurs so frequently that MailMate is almost unusable.

According to [1], that error "is a Microsoft's mechanism to shut down chatty clients. The solution would be to login to this account less frequently.". I have looked for settings in MailMate to reduce the number of concurrent connections, for example, but haven't found anything.

Is there a workaround?
