Comment 3 for bug 2004480

It seems there's no issue with the build 102.7.1+build2 on Ubuntu.

For all users of Office 365 Enterprise searching for a solution: Thunderbird application ID has been changed in version 102.7.1 and the name of the application is "Mzla Technologies Corporation", which makes it difficult to find by your organization's Azure administrators.

In short, after an upgrade of Thunderebird to 102.7.1, you'll be redirected to Microsoft page where you need to enter your login / password + Multifactor authentication (MFA), then you'll see a screen with "Approval required", where you may add request comment to be sent to Azure admins. When the request is sent, Azure admin can validate it using the link:

https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753

({tenant-id} should be replaced in the above link)

This solved the issue for our users.
