Unless you specifically paid extra for a license of ms office, this is just the trial crap bloatware they include with new PCs. You still have to pay for it if you want to use. I’ve heard you can get really cheap activation keys from certain “cd key” sites.
If you go to the “about” section, it will give you more detail. Or, if you brought it from a reputable shop, bring it back to them and ask them why it says this.

If you happen to have a .edu email address, most schools tie it to a license and you can use the school credentials as a license. Ymmv.
You say it was a reputable store. But you have no license for office and a warning about it being an illegitimate copy installed.
I would be taking it back to the ‘legit’ store and asking questions.
