I recently applied SP1 to our Exchange Server 2007 and now receive a certificate error when opening outlook stating that the certificate is expired. To my knowledge we are not runnign a certificate. Any help would be appreciated.
Why would apply a service pack on your main server without testing it on another setup? Unfortunately I don't have an answer for that since I'm using Exch Serv 03. I would say try uninstalling the service pack first then if that doesn't work call tech support. Unless someone else in here can help thats all I got bro sorry.
