5 checks to determine if Microsoft 365 is down or your device is at fault

Microsoft 365 users experiencing outages can determine whether the problem lies with Microsoft or their own device by checking five key sources, ranging from official status pages to crowd-sourced trackers. Microsoft's public status page at status.cloud.microsoft lists service-specific incidents for Outlook, Teams, SharePoint, and OneDrive without requiring sign-in, while administrators can access the Service health dashboard in the Microsoft 365 admin center for tenant-specific issues. Microsoft's official X account @MSFT365Status provides public incident updates, and independent trackers like Downdetector show user-reported spikes that may indicate widespread problems. If no outage is reported, users should test on alternate networks and devices, try browser versions of apps, and verify account credentials and licenses. For organizational users, checking with IT teams about tenant-level incidents can help rule out local issues before troubleshooting further.
