Looking at the requirement page, SOLIDWORKS | Hardware & System Requirements | SOLIDWORKS , it says that for solidworks 2017, only 2010, 2013, & 2016 office is supported.

While I have 2017 solidworks and 2007 Office, it still works. I'm trying to see how much of a problem this would be if I Upgraded to solidworks 2018 and beyond.

Is there a minimum requirement for Office for each solidworks release? If I have to upgrade, I need a clear reasoning to justify the cost.
