Exchange Online OWA “500 Something went wrong. Repeating redirects detected”

Scenario: When attempting to access Outlook on the Web (OWA), you receive the following error:

Solution: This was a Microsoft issue. Their frontend servers within the Exchange Online environment were erroring out. In our case we were impacted well before the global Microsoft incident/advisory was issued (Ex231181). We did notice that it was the same frontend server being reported in the error details amongst all impacted clients, it just took a while for Microsoft to acknowledge the issue. I did see other articles suggesting it could be Microsoft Admin rights and roles assigned to the user, but in our case these were just normal users that were being impacted.
