Mobile App - emails not syncing and not able to log in after deleting app

Hello,

I have had my hotmail account for 20+ years, and never had an issue with the mobile app. Just a few days ago emails stopped syncing to the mobile app. I did all the trouble shooting recommended, deleted cache, removed my account, removed the app, restarted the phone, hit reset.... etc. Nothing has worked. I am now not able to log back into the app as it states unable to process the request at this time. I called Microsoft, and got no where. They sent me this link to ask in a group setting. Can anyone assist? My hotmail account is working on a browser and not the app.

I have the most up to date version of the app as well.
