Again, how are you trying to activate? If he shared his family plan with you, it's already activated. Log into https://account.microsoft.com/services with the account he shared it with and install it there.
Hi. I'm Brian and I'll try to help.
Is this a new subscription? Where did you buy the subscription? Did you get it from Microsoft directly or from another source? If the latter, did you get a product key?
It is my husband’s account he purchased a few years ago from Microsoft with the family plan. I was able to use it before on my old MacBook Air 2015 but it aged out. I purchased a new MacBook Air 2026 but it always shows error OxO and I cannot activate.
thank you for your possible help.
