The RETR command did not succeed.
Need help in the following error message. Is this a problem with Thunderbird or it is a problem with MS outlook365? Any solution to fix this?
The RETR command did not succeed. Error retrieving a message. Mail server outlook.office365.com responded: Server Unavailable. 21
