Microsoft reporting M365 Service Issues

Description

Microsoft is aware that users are experiencing issues accessing Exchange Online mailboxes, and is investigating the issue.

Delivery of new email messages is currently interrupted, and the Outlook mail client may fail to load on desktop, mobile, and web. Users who already have Outlook open may see core features unavailable or disabled. Teams features that rely on Outlook for notifications and scheduling are also experiencing an interruption in service.

Other Microsoft 365 services may be impacted as well.

Microsoft will post updates to Microsoft 365 Status (@MSFT365Status) / X.
