Update
Microsoft continues to investigate and work to resolve an ongoing service degradation affecting multiple Microsoft 365 services, including Exchange Online, OneDrive for Business, SharePoint Online, and Microsoft Teams.
Users may experience the following:
OneDrive for Business and SharePoint Online
Users may be unable to load or refresh portions of OneDrive and SharePoint, including account and storage information, search results, Favorites, Followed and Shared With Me content, recent files, lists, and news. Some users may experience delayed or failed file opening, Office policy-label retrieval, OneDrive synchronization, mobile camera uploads, and video playback. Users may see partial page failures, missing or stale content, repeated retries, or operation timeouts rather than a complete service outage.
Exchange Online
Users may be unable to connect to Exchange Online or may experience degraded functionality. All connection methods may be affected.
Microsoft Teams
Users may experience issues with calendar functionality and search. Presence information may be stale and may not update automatically or through manual adjustment. Users may also experience issues when attempting to update their location.
Microsoft continues to investigate the underlying issue and work toward remediation. IIT (Instructional Innovation and Technology) is actively monitoring Microsoft’s progress and will provide additional updates on status.gsu.edu as more information becomes available.
