Windows 10: Cannot add 'Other User' Error message = this isn't MS account but is.

    Cannot add 'Other User' Error message = this isn't MS account but is.


    I have purchased an Insignia Tablet running Windows 10. I have set it up with my MS 365 account and everything went properly. When I tried to add a second user, as soon as I enter the email, I get "Looks like this isn't a Microsoft account. Try another email or sign up for a new one". But it IS a MS 365 Premium account just like mine, and it needs to be this email address because everything is tied into a workflow environment. How might I make this work?

    Hi dwelch. Welcome to the TenForums @dwelch

    Started googling your issue (searched Looks like this isn't a Microsoft account Office 365). Some of the hits were old but the gist was they are validated differently.

    You mention workflow so I imagine this is an organization and you might be using Active Directory so maybe this link applies.

    The symptoms seems very close. Do you have formal support with MS?

    Maybe the above will at least point you in right direction. Another member may have a better solution.
