Outlook is constantly refreshing - what can I do?

Any update on this? Webapp has been borked since late January.

This reload/refresh loop behavior seems to happen regardless of browser (tested on Edge, Chrome, Firefox), regardless of OS (Windows 11 / MacOS 15.3), and regardless of using outlook.office.com/mail or outlook.office365.com/mail.

Clearing cache/deleting all browsing history solves the issue temporarily - the Outlook webapp will behave for a half day, maybe a day after that. Then, inevitably, will get stuck in a refresh/reload loop upon user action (replying to an email, accepting a meeting invite, etc.).

My hunch is that this bug is tied to authentication and/or session logic - a token or some session cookie the webapp uses is expired, but the user is still logged into to their Microsoft account and some type of auth object still exists so Outlook tries to logout/reload because the code thinks something is expired, but the app then recognizes a session object still exists and logs back in - landing you at the "inbox home screen" with a now saved draft or unaccepted meeting invite, repeat.

The URL (outlook.office365.com instead of outlook.office.com) was honestly life-changing for me, recommend this since it's super simple and seems to be effective!

So we are all having the same issue. Constant refresh and clearing out the history and cache only is a temporary fix. Microsoft, do you have a different resolution yet?

Same issue.

Latest version of Edge (just updated) on PC (Win10)

Unable to do my work.

Frustrating.

Same issue in Google chrome running in browser on windows machine. No issue if I open in Edge browser.
