Microsoft reports service disruptions affecting Outlook and Teams
Microsoft said users in the Americas experienced problems accessing Exchange Online mailboxes and Teams, attributing the issue to unavailable servers and elevated load across regions.
Microsoft announced on Thursday that some users were unable to access Exchange Online mailboxes through various connection methods in the Americas and reported difficulties with Microsoft Teams functionality in North America. The company said the mailbox problem stemmed from a number of servers unexpectedly becoming unavailable, which strained the remaining infrastructure despite traffic levels remaining stable.
In response, Microsoft said it had paused all deployments, redirected traffic away from the affected infrastructure and restarted the impacted servers to restore service. The firm added that the issue could affect Microsoft 365 connectivity for users in any region.
Microsoft later reported that mitigative actions had restored Teams service health and functionality. Outage monitoring site Downdetector also logged reports of problems with Teams, Outlook and other Microsoft products on Thursday.
