MS Office tells me it is not Genuine

[BDux82]

Lately, whenever I start a session with an MS Office application, I get a
message that the copy of Office I am using is not genuine.

I own 2 computers and own 2 MS Office licenses, and I am not entirely sure
which copy of Office was purchased for which PC. I suspect that the source
of the not genuine message is that I may have used the same disk and/or
license key to install Office on both of the computers.

Is there any way to look at my installed Office instances to determine what
key was used on what PC?
