Is there a way to emulate Edge, Chrome, or Firefox in the browser window opened for Oauth2 or open Oauth2 authentication window in another browser? I'm trying to access an Office365 corporate email using Thunderbird 102.8.0 on Windows 10. It used to work until recently, when the corporate IT decided to require "approved browsers" for the login which do not include Thunderbird built-in browser.

No, that's not possible. But I don't see any reason why this shouldn't work with Thunderbird. Wrt Office365 accounts, this may need Administrator approval once though. See https://blog.thunderbird.net/2023/01/important-message-for-microsoft-office-365-enterprise-users/
