Following on from another post i made:
I am having an issue with a certification error between my Outlook Clients and Exchange Server.
I enabled a purchased 3rd party UCC Certificate through Exchange Powershell to allow http over RPC from external. My initial problem was that I did not add all of the required alt names to my first cert. Now everything is working (external clients, OWA) but outlook clients are getting a certificate error on initial connection on our internal network.
The error is telling me that "the name on the security certificate is invalid or does not match the name of the site" and the site to which it is trying to cennect is "Sites"
Sites is a cname that SBS puts into DNS to resolve to it's IIS applications (e.g. http://sites/owa
). I dont know why Outlook is coming back with this eror (it should be retrieving data from servername.domain.local, which is an alt name on my certificate).
I have even tried deleting my outlook profile and re-connecting to clear out any links that I may have previously created.
Any ideas why Outlook would connect to sites and get this error??
