Sending, receiving, and organizing email in Outlook on the web for business
Hi Karen,
I completely understand how disruptive it is when your email isn't working as expected, especially during your workday.
Currently, Outlook is experiencing a service issue (Incident ID: MO1550821), which is classified as Service Degradation. Please rest assured that Microsoft’s engineering teams are treating this as a priority and are actively working behind the scenes to resolve it and get everything back to normal. While they haven't shared an exact Estimated Time of Arrival (ETA) for full recovery just yet, mitigation efforts are underway.
If you'd like to follow real-time progress, your IT team can keep an eye on the official updates in the Service Health portal:

Your patience and understanding during this disruption are greatly appreciated. Hopefully, full service will be restored shortly so you can get back to your work without further interruption.
