Using classic Outlook for Windows in business environments
Hi Gordon,
Microsoft 365 is currently experiencing an outage impacting several services.
While your IT team is monitoring the situation (admins can view details via Issue ID MO1550821), there is nothing you need to do right now.
Because this is a backend service interruption originating from Microsoft's infrastructure, there are no troubleshooting steps or corrective actions required on your part. I appreciate your patience while Microsoft work to resolve the underlying issue and restore normal service operations.
Since I am a fellow Microsoft user, I am unable to provide an estimated time for resolution.
Nevertheless, you can also follow official updates via @MSFT365Status on X.
