This is SBS2008/Exchange 2007 with XP Pro clients
All but one client has no problems. Just one client is getting a certificate error in Outlook. The error is:
"The name on the certificate is invalid or does not match the name of the site."
It asks if I want to continue, if I click 'Yes' the process seems to complete, but there is a Send/Receive error at the bottom right. When I click this is says:
"0x8004010F The operation failed. An object could not be found."
It gave me the option to install the certificate. Doing so made no difference to the error.
If I log onto that same workstation as a different user, there is no problem. I logged in again as the original user and deleted/recreated the Outlook profile. The original problem still persists.
