In a service alert (MO1068615) in the Microsoft 365 admin center, the company says impacted services include but are not limited to Microsoft Teams, adding that the most likely cause could be a faulty routing configuration for its Azure Front Door (AFD) cloud content delivery network. Since the incident started over two hours ago, outage monitoring service Downdetector has received thousands of user reports, with most affected users saying they're experiencing server connection and website problems when trying to access Microsoft 365 services and features. In March, Redmond mitigated another outage that affected Teams customers, causing call failures and impacting other services such as Outlook, OneDrive, and Exchange Online, preventing users from checking email messages. While the company has yet to share more information on the outage's root cause and how widespread it is, Microsoft tagged this as a critical service issue in the admin center, which typically involves noticeable user impact. "We're investigating an issue impacting multiple Microsoft 365 services and features in the North America region," Microsoft confirmed via its official Microsoft 365 Status Twitter account. The same month, it addressed an issue that prevented Outlook on the web users from accessing Exchange Online mailboxes and a week-long Exchange Online outage that caused delays and failures when sending or receiving email messages. Microsoft is investigating a new Microsoft 365 outage affecting multiple services across North America, including the company's Teams collaboration platform. More recently, in April, Microsoft fixed an issue blocking IT admins worldwide from accessing the Exchange Admin Center (EAC). "We're reviewing Azure Front Door (AFD) routing configurations and networking telemetry to isolate the source of the issue," Microsoft added.
