Outlook outage: Microsoft reports 'issues' with Teams and email
The company posted about the disruptions on social media.
Microsoft reported issues with users' Exchange Online mailboxes and an issue with Microsoft Teams, according to posts on social media Thursday.
"We're investigating reports of users experiencing issues accessing Exchange Online mailboxes through multiple connection methods in the Americas," the company wrote, after first reporting "users experiencing issues when accessing or using Microsoft Teams functionality in North America."
"We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable; straining the remaining infrastructure.
The company initially said the issues involving Exchange Online mailboxes could be due to infrastructure "experiencing elevated load across multiple regions."
Later, though, Microsoft clarified, "We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable; straining the remaining infrastructure. "
Regarding the issues with Microsoft Teams, the company followed up shortly after first reporting the issue, writing, "Our mitigative actions have successfully restored service health and functionality."
Downdetector, which monitors outages, reported issues with both Microsoft Teams and Outlook, among other products on Thursday.
Regarding the issues affecting Exchange Online mailboxes, the company added, "we've confirmed the issue may affect Microsoft 365 service connectivity for users in any region."
The company continued to provide updates on the potential fix to the mailbox issue on Thursday, and added, "We're aggressively pursuing all pathways to reduce impact. We've paused all deployments, we're moving additional traffic off the affected infrastructure, and we're restarting affected servers to return them to service."
