I believe I have created confusion is sign up for Microsoft 365 - it appears that I inadvertently purchased three (3) subscriptions to 365 --- now when I attempt to 'activate 365" I get the error code 0x0 ---- but I can't figure out how to correct this --- it indicates that I am trying to sign into the "wrong" Microsoft 365 subscription-- I'm used the same email for all purchases.

    If you are seeing the 0x0 error, that is a widely reported error since the July update on the Office apps on an Apple Mac computer.

    1

    At the top left of your Desktop, click the Apple icon and select 'About this Mac', what version of MacOS is installed on your computer?

    2

    Log into your Microsoft account on this link, check the expiry date on the Microsoft 365 subscription is that listed correctly for your subscription payment.
