I suspect my outlook 2010 uses the wrong certificate that was never assigned by me (I am also the admin) to be the correct certificate. Maybe I should use my current certificate. How can I make them know on each other's use ? How do I attach it to my Exchange and to my Outlook ? One of my problems is that I don't exactly knows which certificate my outlook should use.Īnother question is should I issue a new certificate ? which ? where (Local CA ?) ? I read the forum and search the internet but didn't find the answer with that combination outlook 2010 and exchange 2003.Īny ideas on how can I reconnect my outlook to exchange back again. The outlook 2003 still connects to the same exchange server with no problem. I have another client computer (my laptop) with windows 7 64 bit and *** outlook 2003 *** installed.
