Self cert issue

[Glanza]

Starting to pull my hair out on this one,

Clients server self cert was due to expire at the weekend, I ran the wizard and it's now extended to 2017 however I've now got an issue with remote clients outlook not syncing with the following error:

The security certificate is not valid & There is a problem with the proxy servers security cert.

I've installed the cert and it imports ok but still have the above error.

Been searching through google but not having much luck. Any advice?

It's Exchange on SBS 2008, It's a self issued cert on that box.

The remote users have laptops that are connected to the domain. If i connect to the VPN then try outlook it'll still warn about the cert but their mailboxes will update.

This isn't my usual field so apologies if I'm not making much sense.

Got it to work by manually installing the cert to both trusted publisher and root on the test PC.

Will now roll it out to the others, thanks for your help.
