Microsoft has confirmed that it is investigating reports of users experiencing difficulties accessing Outlook and Teams. A Microsoft social media account dedicated to reporting service incidents announced at 9:40 a.m. that it had identified access issues with Teams, followed by a subsequent update at 10:13 a.m. indicating that remediation efforts were beginning to mitigate the impact.
The account issued a further update at 11:54 a.m., confirming that users were also encountering difficulties accessing Exchange Online mailboxes. Exchange Online is the web-based messaging service through which users connect via Outlook.
Outage reporting platform Downdetector recorded more than 100,000 reports of Microsoft Outlook issues at approximately 12:15 p.m.
The University of Missouri , identified by Regional Economic Development Inc. as Boone County’s largest employer , operates on Microsoft 365. The university’s IT status monitoring page indicated just before 1:00 p.m. that technicians were actively investigating reported difficulties employees were experiencing when attempting to access their campus email accounts.
In a subsequent update issued at 2:30 p.m., the university confirmed that email services for both MU and MU Health Care had been affected, with Teams, SharePoint, and OneDrive also impacted by the disruption.
“These are operating, but at a degraded level in some instances,” the update read. “Microsoft is working to resolve the interruption, but has provided no estimated time for service restoration.”
