As per the reported updates, the disruption is attributed to elevated infrastructure load across multiple regions, resulting in connectivity and service accessibility issues.

This disruption is impacting business operations and user productivity. We request your team to prioritize the investigation and provide the following information:

What is the confirmed root cause of this widespread service disruption?

    Outlook services appear to be recovering. If you are still experiencing connectivity or synchronization issues, please follow these steps:

    Close the Outlook application completely and reopen it.

    Wait for approximately one minute to allow Outlook to reconnect and start syncing with the server.

    Keep Outlook open and allow sufficient time for synchronization to complete.

    1. If you have emails or requests waiting in the Outbox or sync queue, allow Outlook to process and synchronize them with the server.

    working fine now
