Hi Team T,
I apologize for the late reply. As mentioned in the banner on the community, there have been some issues with the notification system recently, and the support team has not been receiving any responses. I need to respond to a large number of threads daily, so it took me some time to locate your thread. I apologize again for the delay in my response.
About your issue: Uninstalling and reinstalling the Microsoft To Do application usually clears the login credentials in the app. However, if you have already tried this step, you might consider creating a new local account on your Mac and logging in. It's possible that certain system files are affecting the Office update of login credentials.
