Massive service outages leave Microsoft 365 offline, impacting thousands of customers: Report

More than 15,000 people were unable to use Word and Excel on Monday, according to the outage monitoring website At least three disruptions of Microsoft services have occurred since the year’s commencement.

According to Downdetector, Microsoft Outlook, which is utilised by millions of these businesses to maintain smooth working, has been experiencing outages.

One user commented, “Outlook on the Web not working.” An error notice displays while attempting to visit the email website. It displays “Service Unavailable,” then “HTTP Error 503.” The service is not accessible. “We’re looking into a problem with using Outlook online. More information may be obtained in the admin centre under EX571516, according to the business.

“In an effort to determine the fundamental core cause of the problem, we are now analysing our networking infrastructure and most recent changes. In the admin centre, look for EX571516 for more details, according to Microsoft’s tweet.
