mbsync - IMAP command 'NAMESPACE' returned an error: User is authenticated but not connected.

Hello - I'd like to incorporate oauth2ms to manage outlook.com (MS public email domain) emails with mu/mu4e with mbsync. I'm able to successfully create credentials.bin with oauth2ms on command line. But when syncing, mbsync returns this error.

I noticed Issue 27 with the similar (same?) error code, which was raised more than a year ago, but don't see a solution posted there. Any suggestions greatly appreciated.

Thanks!
