Hi,

Edit Jul-10-2025 / 10 AM

About to be fixed. Thank you all for the patience.

https://status.cloud.microsoft/m365/referrer=serviceStatusRedirect

Current status: We’ve begun a broad expedited deployment of the configuration change across all affected infrastructure. We expect most impacted users will experience relief within the next two hours, as the fix saturates the environment.

We’re closely monitoring service health telemetry to ensure the recovery continues as expected. We understand how impactful incidents of this type can be, and we're continuing to open any additional workstreams to expedite recovery and restore availability.

Start time: Wednesday, July 9, 2025, at 10:20 PM UTC

Next update by: Thursday, July 10, 2025, at 6:30 PM UTC

    People, after all this posts here is it so hard to understand that absolutely nothing we can't do to fix it. Password change, clearing the cache, whatever you do, nada, niente!!!

    The problem is on the Microsoft side, not on your. Obviously the whole world is affected.

    All what we can do is just wait for them to sort it out.

    It's a shame for a company that they're still silent about it, no official statement or anything. Very bad Risk and Crisis Management.

    FYI - from Microsoft site update:

    Outlook.com Service degradationUsers may be unable to access their mailbox using any connection methods

    User impact: Users may be unable to access their mailbox using any connection methods. More info: Impacted connection methods include, but may not be limited to: - Outlook.com - Outlook Mobile - Outlook desktop client Current status: We're continuing to apply the configuration changes to fix the underlying problem and completing additional validation efforts to ensure authentication components are properly configured. In parallel to the current deployment of the configuration change fix, we're reviewing options to leverage an expedited deployment methodology in regions which are experiencing the highest levels of impact to provide the most effective relief where possible.
