EXCHange 2010 Access from outlook using rpc over http failing
Posted on 2011-03-08
I am having several problems trying to connect outlook clients directly over the internet.
Also, I can't ping my external address from inside my firewall.
What I have is my internal exchange server exch.wot.local with and internal ip xxx.xxx.xxx.212
My external address is post.wot2.com which uses NAT to point to the internal IP
I have port 25 coming in and routed through a spam filter
Other ports such as 80 443 110 220 143 I have open pointed directly to internal exch server.
I have installed certificates from godaddy using the external name however I get a warning when running testexchange tool:
"The test passed with some warnings encountered. Please expand the additional details.
ExRCA can only validate the certificate chain using the Root Certificate Update functionality from Windows Update. Your certificate may not be trusted on Windows if the "Update Root Certificates" feature isn't enabled. "
When running the test-outlookwebservices it passes on on the internal exch.wot.local
but fails on all the post.wot2.com address.
dns issue? firewall?
Outlook web access works as does POP3, Iphones and droids. Only outlook is giving me grief.
Thanks for all the help.
