Exchange 2013 - outlook 2013 connects through windows 10 but not on windows 7 computers

New exchange 2013 install with coexistent with exchange 2007 to move mail boxes. All data moved over. installed go daddy ucc certificate. Everything working. After updates and a reboot of the server outlook 2013 or outlook 2010 on win 7 machines will not connect to the exchange 2013. Same account set up on a win 10 with outlook 2013 or 2016 connects. SSl now fails connectivity test.  

Had to adsi edit remove the public folders from the exchange 2007 box. We didn't use them. don't think this could affect it but thought I would throw it in.

I ran check with digicert and the ssl chain is good. All phones and remote outlook 2013 on win 10 work remotely.

I have been over all urls on the virtual directory's and autodiscover. They are correct

Nothing in the event viewer.

The Microsoft Connectivity Analyzer wasn't able to obtain the remote SSL certificate.

I cannot find anything causing this

Any ideas greatly appreciated.

Why would outlook 2013 or 2016 on win 10 connect and on win 7 machines not?

How can the connectivity analyzer fail with below and our remotes all work?  

thanks in advance
