Microsoft 365 is down again today. This hardly sounds new or surprising to many as it is almost a weekly occurrence.
The official access to Microsoft 365 status on Twitter (now X) confirmed the issue and explains that users cannot send or receive messages properly in Teams. Affected users experience delays or notifications fail entirely. The issue is apparently limited to the United States only according to user comments. More details are available TM675041 in the Service Health Dashboard in the Admin Center.

Another recent example of such an outage occurred about a week and a half ago when there were reports of Microsoft 365 servers being down as users were unable to access services such as Microsoft Exchange, Outlook, Teams and OneDrive. Although Microsoft never officially acknowledged the problem, there were huge spikes in the downdetector.
Microsoft experienced a major global outage in early June for many of its online services, including Microsoft Exchange, Outlook, Teams and OneDrive. It was later revealed that the outage was caused by a massive DDoS cyber attack directed at the company.
Other online services were hit with brief outages later this summer, including Microsoft 365 services later in June, followed by problems signing in to Microsoft Teams. The latest issue came up in July when the company said people were experiencing problems with Access to SharePoint Online and OneDrive for Business. The problem was solved within a few hours.
