Dear Raikwar, Mahesh
There is currently a widespread Microsoft 365 service disruption affecting multiple services, including Exchange Online, which provides the email functionality for Outlook. As a result, users may be unable to access their mailboxes through Outlook on the web, desktop, or mobile devices. Email delivery may also be delayed.
According to the latest update, the Microsoft 365 team is seeing positive results from restarting the affected infrastructure and is monitoring server stability while continuing its recovery efforts. However, full service restoration has not yet been confirmed, and no specific recovery time has been provided.
You can check the Microsoft 365 Service Status for the latest updates.
I recommend checking the service status page periodically and avoiding major changes to your Outlook configuration while Microsoft continues working to restore the affected services.
