Error Adding Microsoft 365 Email Account

Satisfied and experienced Thunderbird user her, but have hit a point of confusion. When attempting to add a Microsoft 365 email account, everything goes 'as expected' until I go to the Inbox and see emails from a previously added Microsoft 365 email account. I feel like there's probably a saved OAuth2 login somewhere or some other thing being used instead of prompting me for the new login credentials.

Thanks in advance for any assistance,
