Microsoft have reported an incident that occurred yesterday evening with their Exchange service. The issue, which primarily affected Outlook on the web, prevented users from connecting to Exchange. Affected users would receive an error message containing the following:
“AADSTS50011: The reply URL specified in the request does not match the reply URLs configured for the application:”
The issue was found to be a recent update that caused problems with authentication. The problematic update was disabled and Microsoft have confirmed that the issue is now resolved.
