Outlook and certificate nightmare

Hi People.

I have been using a Outlook and backend IMAP linux server for years, and have used a self signed cert. Something has changed on the last update to either the server or the Win7 workstations.

Usual message about certificate, so open IE with admin rights, go to mail server website, install cert into Trusted Root, then modify the host file to fake the name:- mail.server.local mail.server.com
This would normally allow Outlook to work fine, without moaning about the certificate.

Cert Expired.
I am sure I am missing something basic here, as I go through the same procedure as above, however there is now a slightly longer message saying "See attached image" And when I view the certificate it shows the expired one? Baffled?

Ran certmgr.msc and removed all versions of the certificate for the server, installed them as above again. Same end result as the attached image!

I am rather at a loss, suppose I could consider buying a cert, but always being short of money it would be a last resort.
