Perhaps a tall order, but would be helpful if you could within the blog post link to whatever documentation MS might have for admins implementing this (probably in office365). There will be a non-zero amount of smaller orgs where following an official guide will be the only way this happens.

UPDATE:
We have delayed further rollout of Thunderbird 102.7.0 while a suitable patch is implemented to resolve a critical OAuth issue

If your client was already upgraded to 102.7.0 and you wish to use a previous version for the time being, please install and launch an older version, for example, 102.6. Thunderbird should automatically detect your existing profile.

However, you can launch the Profile Manager if needed by following these instructions: support.mozilla.org/en-US/kb/p…

profile manager create and remove thunderbird profiles | Thunderbird Help

Thunderbird stores your personal information and settings in a profile folder. Learn to work with different profiles on Thunderbird.

UPDATE:
A solution to the authentication issue will ship with version 102.7.1, releasing during the week of January 23.

Version 102.7.0 is now available for MANUAL download only, to allow unaffected users to choose to update and benefit from the fixes it delivers (thunderbird.net/en-US/thunderb…)

Please note that automatic updates are currently disabled, and users of Microsoft 365 Business are cautioned to not update.

How do I download 102.6. You have deliberately made it very difficult to find previous versions.
