Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Carol,
I'm not a lawyer, and I'm not in Canada (just a few feet away, but still not technically in Canada), so I can't give you legal advice. From the technical side, Microsoft kept the activation servers running about two years longer than they promised they would when support for Office 2011 was discontinued. The activation servers now seem to activate only brand new never been used product codes, but do not work at all for previously used codes. Every once in a while someone reports success on reactivation, but that seems to be the exception, not the rule.
You have some options (besides trying to start a lawsuit)
Are you a student, faculty or staff at an educational institution? If so, lucky for you! You get a free Office 365 subscription
You can use the free on-line "cloud" version of Office at OneDrive.com
You can install Libre-Office (it's free. Not as good, but might be good enough)
You can buy an Office 365 subscription.
