  • Hi Ziggy,

    Are you the admin of your Office 365 tenant? Based on the error message, the issue occurs to the user account name. If you are not the administrator of your organization, please contact with your admin to double check what your user account is.

    Meanwhile, when you mention “can’t access to my Office 365 account”, what are you trying to access? The portal address of Office 365 is Please use your account to access this URL and check whether you can login successfully.

  • Hi,
    I'm a Admin and I have previously worked on my side, but I can't access my account. I do not know where I made a mistake, but tried everything.

  • Hi Ziggy,

    Thanks for your above screenshots provided.

    Since you have registered your account but it still promotes that your user ID does not exist, a possible root cause is you have changed your email address to use your vanity domain at Office 365 Portal.

    With the information you provided, I checked your tenant information in our system, and found that you had added your customer domain name ( to your Office 365 account. In this situation, I suggest you try to log into Office 365 Portal with as user name(change xxx to your own domain name). You may need to reset your password if you still can’t get logged in.

    Please let us know if we can further assist.

    Can you assist me to get Access on the site again?

    Best regards
