Outlook/Email/Team connectivity issue

Microsoft is currently reporting a Microsoft 365 service degradation in which users may be unable to connect to multiple services, but no confirmed public restoration time is available at present.^1^

The reported Exchange Online send/receive failures and Teams connectivity problems are consistent with that broader incident. Avoid changing Outlook profiles, reinstalling clients, or modifying mail settings while the incident remains active.

Check your tenant-specific status and ETA

A Microsoft 365 administrator should:

1. Sign in to the Microsoft 365 admin center.
2. Go to Health → Service health.
3. Under Active issues Microsoft is working on, open the Microsoft 365, Exchange Online, or Teams incident.
4. Review:
   • Status
   • User impact
   • Last updated
   • All updates, where Microsoft posts recovery progress and any estimated restoration time

Service health can be viewed by users assigned an appropriate role, including Service Support Administrator or Helpdesk Administrator.^2^

The status meanings are:

• Restoring service: Microsoft has identified corrective action and is bringing the service back to health.
• Extended recovery: most users may recover first, but restoration across all affected systems will take additional time.
• Service restored: Microsoft has confirmed that corrective action resolved the issue.^2^

If the tenant dashboard does not show the incident, select Report an issue on the Service health page. Microsoft will compare the report with telemetry and reports from other organizations. Administrators can also open the incident and select Manage notifications for this issue to receive status updates.^2^
