If I try to activate using the Product key, I get invalid product key error. If I tried to activate by signing into Office 365 subscription I get the below error
Error "Sorry, there was a problem while trying to connect to your account. (Error code:0x80072f17)"
I am able to login to www.office.com/myaccount using my email address and password. I even changed my password and tried to activate using the new password but no luck.
