The bookedmark link I've been using for Outlook that worked yesterday no longer works. It sends a Redirect. The same link continues to work on other browsers.

This is the message that came up for me to copy to the administrator. Does this help?

There was a Service Health incident on my Exchange Server. They were working on it since about 10:30 AM PST and it was resolved with the message: "Additional investigation determined that a recent change contained a code regression that resulted in authentication failures within the Outlook on the web. We've disabled the deployment and are currently in the process of rolling the affected change back to mitigate impact."

I'd check to see if it's working for you now.
