Issues with Outlook 2010 Sending Mail following RHEL7 QMail update...

Just a thought, they might have removed support for older TLS. I did this myself a while back so I could past those PCI test. I think on some Windows 7 computers you have to change some config so that they will use the updated TLS as well. Not sure if this is your issue, but worth looking into.

Thank you Sir... That was my thought as well and it turned out to be the case. We did the Registry changes on the affected machines as documented by Microsoft and the issue was resolved.

Thanks again!

Take a look at these two threads back from when I was dealing with this.
