A number of cloud-based Microsoft products are having issues right now, apparently as a result of an Azure Active Directory issue. Over the last hour or so many users have been unable to access Microsoft Teams, with the company’s 365 Status Twitter account tying it to a recent change to an authentication system.

The bad news is that the list of services affected is long including not just Teams, but also Office, Exchange Online and Yammer. Xbox Live is also mentioned as one of the services experiencing issues, however its status page only notes a problem for anyone trying to redeem a code right now.

The latest update as of 5:17 PM ET notes that a full remediation is expected within the next 60 minutes, so if your office uses Teams you know when to check back in.

We are currently rolling out a mitigation worldwide. Customers should begin seeing recovery at this time, and we anticipate full remediation within 60 minutes. Additional information can be found at https://t.co/AEUj8uAGXl or under MO244568 if available.
