A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
This essentially means
- You are using a business version of Microsoft Office
- While the software may be installed on your machine, an underlying license has not been assigned for the software to work.
Can you share how you came to get this Microsoft Office?
If its purchased for your company and installed on your machine then, you (if you are admin), or your company admin needs to assign a Microsoft365 license to you, examples of these licenses are Microsoft365 Standard, Microsoft365 Apps for Business, Office365 E3, Microsoft365 App for Enterprises.
One remote possibility is you acquired the license (very highly discounted) via online sellers. Unfortunately, many of these highly discounted licenses are unused corporate or educational licenses peddled on the side by dubious company admins, and the license can be pulled anytime when discovered or used by the actual owners. As such we have seen licenses stop working a few months into their purchase although many of these sellers claim lifetime or permanent license usage. May not be your case.
There may be other possibilities but these are the ones I can think of at the moment.
