Good day Richard,

Microsoft has officially posted an active service degradation advisory in the Microsoft 365 admin center regarding this outage (tracked under incident ID MO1550821). They are currently investigating a widespread service degradation preventing users from connecting to multiple Microsoft 365 services, including Outlook and Exchange online.

User's image

Currently, Microsoft is actively investigating the issue on their end, so there is no action needed from end users at this time.

In the meantime, please ask your IT administrator (if they still have access to the Microsoft 365 admin center) to monitor MO1550821 under Health > Service health for further updates. Having them use the "Report a problem" feature will also help Microsoft log the impact on your organization's tenant.

I hope this information is helpful.
