Hi,

Wonder if you can please advice me on this urgent issues we have at our business. For some reason Thunderbird email is prompting to enter the password. When doing so it says "Login t server xxxxx365.com with username xxxxxxx@xxxxxx.co.uk failed ! "

Any reason why this is suddenly happening ?

I also called Microsoft our email service provider and all seems find at their end

Many thanks Regards Stavros

In preparation of an upcoming change on their infrastructure, Microsoft attempt to get people to migrate to modern authentication i.e. OAuth2 by temporarily switching off the legacy authentication mechanisms for 12-36hrs for all their tenants accesing eMail via IMAP or POP. So maybe it is your companies turn right now...

Solution should be to change the authentication method for the IMAP and SMTP server in Thunderbird to OAuth2. You should then be taken through a web-style login process on the Microsoft servers.
