Impossible to connect a Microsoft 365 account

Hi, I use a old Thunderbird version (38) for Windows Serveur 2003 and I can't connect a Microsoft 365 account. He indicate " A error with login or password" (screenshot in attachment). My password is correct, because it is OK with an other computer with recent Windows and Thunderbird version. I think the problem is with OAuth. Do you have a solution ? Thank you for your support.

I don't think OAuth was supported in TB until about v. 60 or 68. I would create an app password on the O365 site and see if that works.
