My PC died, so my OEM copy of Office Professional **** resides on the SSD drive that I took out of the dead PC and installed into a new PC with an HDD drive. I swapped out the HDD for the SSD and now Microsoft is telling me my Office Suite will expire in * days and will not function after this.*In addition, Microsoft has an old email address in my Microsoft account thus I cannot get any replies from them as this old email account has been deleted many years ago.

Downloaded Libre Office to use in lieu of Microsoft's arcane licensing regarding OEM cannot be used on another PC when the first PC died. How ignorant is this? Furthermore one cannot call Microsoft for this kind of support if one does not reside in the US. And if that isn't bad enough I tried in vain to make contact with Microsoft to get an old email address removed from my account because I deleted this email account a long time ago and now cannot receive any confirmation messages from Microsoft. What idiots.
