Outlook 2013 have certificate warning with sbs2011 (Exchange 2010). Selfsigned cert is used. Only domain-members have the problem
Posted on 2014-09-12
we have a sbs2011 with Exchange 2010. As domain we have via wizard in the console used remote.realdomainname.com . If i ping remote.realdomainname.com it ping sthe ip of the local server. In DNS there is the right Entry i think. On top we entered the line "192.168.10.2 remote.realdomainname.com" in the hosts file.
We have some workstations which are members of the network-domain and some workstations are only in a workgroup.
Only the workstations which are domainmembers, throw a warning at the start of Outlook. Outlooks says that the certificate realdomainname.com is not valid.
Outlook tries to go out on the webserver a looks at this ssl-certificate instead of looking directly over lan to the exchange-server.
I tried to use proxy-settings in outlook without any success.
Any ideas ?
