Hi @PRASHANT KANDREGULA

Please be advised that there is currently a service interruption affecting Microsoft Office (Incident ID: MO1550821). Microsoft is actively working on resolving the issue to restore services as quickly as possible.

Currently, Microsoft is restoring the system in phases, and some features have started to perform better; however, overall speed and performance are not yet fully stable. Microsoft has not announced an exact Estimated Time of Arrival (ETA) for full recovery, as their engineering teams are still deploying mitigation steps. Your IT team can monitor real-time updates and official timeline announcements from Microsoft via the Service Health portal here:

I'll continue to monitor this case and let you know if there is any update.

Answer 2

Microsoft has acknowledged the multi-service connectivity incident MO1550821, but there is currently no verified completion time or public confirmation of full restoration; check the tenant-specific incident entry for the latest status. ^1^

Check the current incident update

Sign in to the Microsoft 365 admin center with an administrator account.
Open Health → Service health.
Under Active issues Microsoft is working on, find MO1550821.
Open it and review Status, Last updated, Affected services, User impact, and All updates. Service Support Admin and Helpdesk Admin roles can also view Service health. ^2^

Any listed “next update” time is when Microsoft expects to publish another progress report—not a guaranteed restoration deadline. Full recovery is confirmed only when the incident status changes to Service restored.

If the admin center is inaccessible, use the public Microsoft service status page linked from Microsoft’s Service health documentation. End users without admin access should contact their organization’s Microsoft 365 administrator for the tenant-specific update.

Avoid reinstalling applications or changing tenant, account, or network settings solely because several Microsoft 365 services failed simultaneously. If Microsoft marks MO1550821 as restored but your tenant remains affected, use Health → Service health → Report an issue or open a Microsoft support request.
