Exchange Certificate Security

Last Modified: 2013-08-11
Hi Guys,

We just added a new certificate to our Exchange 2007 box (to get our smartphones to receive email) and since this has been installed, all of our users now get a security warning message every time they open Outlook.

I have googled this issue and read through Microsoft's support pages regarding this, but I have yet to find a Microsoft support page that has ever been helpful with any issue I have had, and this record still stands!  ;)

Has anyone come across this before, or knows how to fix it?   It's very annoying.

Note:  A rebuild of the user profile client-side doesn't remedy the situation at all, it seems to be a server-side problem.

Users are using XP and Windows 2007, the problem is identical on all machines.
