Greetings,

I got a new computer and installed all the microsoft 365 programs and various other programs on it. I went to my account to deactivated what I thought to be my old computer, however, it was my new computer as well. When I look at my account both computer have been deactivated and it says to contact my admin to reactivate. Our company doesn't have a an admin. How do I reactivate my new computer?

    When you start an Office app that's not activated, you'll be prompted to sign in to Office. Be sure to sign in using the Microsoft account, or work or school account, that you used to buy or subscribe to Microsoft 365.

    I'd reboot, then try again. Do not sign in to the office.com site, start up one of your office applications and follow the prompts to sign on and activate.

    @DESKTOP-Q73F32B ,

    > I am signed in but my profile show this computer deactivated because I deactivated it by mistake so now when I sign into my microsoft apps I get an error message.

    Could you provide the details or a screenshot of the error message?
    Is your account an AAD account? Was your new computer disabled in Azure?

    1. If yes, you need to find someone who has administrator permission to re-enabled it from the Azure AD blade.
      The similar threads, you may have a look.

      How to re-enable the device
      Besides, to better help you, it's best add the tag "azure-active-directory" to find correct team to help you.
    2. If not, as DSPatrick said, you could re-sign in Office apps with your licensed account to reactivate Microsoft 365 apps after deactivating the device.

    Thanks for your understanding.
