  • Outlook.com won’t let some people log on – 401 error

    Posted on November 16th, 2018 at 12:49 woody Comment on the AskWoody Lounge

    This has been going on since last night, US time.

    @MikeyD215 reports:

    Anyone here experiencing issues trying to sign in to Outlook.com?

    Attempted sign-in results in “401 error: Unauthorized: Access is denied due to invalid credentials.”

    I have succeeded in signing into one account, but cannot sign into a second one. Softies claim problem almost 100% solved as of 10:45 a.m. EST, but complaints still pouring in.

    Affects some accounts, but not all. Occurring around the world. Been going on for over 15-16 hours now. Type of connection not a factor, type of browser not a factor. I am signed into MSN.com and can see my “@msn.com” emails, but I cannot access them in that one email account, but no problem with a different “@msn.com” email account.

    The Office 365 Service health page reports:

    Title: Can’t access email

    User Impact: Users may be unable to access their email.

    Current status: Restarting the affected infrastructure has resolved the issue. We’re continuing to monitor the service and are reaching out to some of the affected customers to validate resolution.

      As of 19:00 UTC they are saying the issue is resolved.

       

      Service degradation

      Latest message:Title: Can’t access email

      User Impact: Users may have been unable to access their mailbox from Outlook, Outlook on the web, mobile devices, or other protocols.

      Final status: After an extended period of monitoring, we have validated that the service has been restored.

      Scope of impact: Impact was specific to users that were attempting to access their mailbox using basic authentication.

      Preliminary root cause: A recent update introduced a configuration issue within the authentication infrastructure, resulting in impact.

      Next steps:

      We’re reviewing our update procedures to better identify similar issues during our development and testing cycles.

      We’re reviewing our monitoring services to look for ways to reduce detection time and more quickly restore service.

      We’ll publish a post-incident report within five business days.

        “Users trying to login with basic authentication”

        I wonder if possibly an issue with web browsers using TLS 1.0? Just a guess.

      Happy to report that I was, at long last, able to sign in to my mail box as of about an hour ago.

      Today Outlook.com is OK.

      Different issue

      Google email accounts occasionally drive me crazy via Outlook, refusing logon. Subsequent manual logon via browser results in finding a message reporting new device (when I only ever use three verified devices). Why Google does not have an option to verify via MAC address instead of their current mystery method is baffling.  Yes you can spoof a MAC address but you could probably spoof the mystery method Google use at present as well.

      They may have fixed outlook.com but it appears they broke something else. I cannot log into the office365 exchange admin page. Getting a 401 error just like it was reported with consumer user logins.
