Outlook Anywhere (RPC-over-HTTPS) in SBS2008 - Timeout
Posted on 2010-09-13
I'm having an intermittent problem with Outlook Anywhere running on Exchange 2007 with SBS 2008 where clients will lose connection and timeout when trying to reconnect. Outlook connection status shows "Connecting" on any or all of the connection types (mail, directory, etc). xRCA shows a timeout during the authentication phase. Browsing to the rpc/rpcproxy.dll just sits there trying to connect. The problem doesn't seem to happen on the SBS browsing to either the name or localhost but does occur on machines on the same LAN as the SBS. I get the "...problem with the website's security certificate" page since I only have the external names in the SSL but when I click to continue, it hangs. External connections don't complain about the SSL since the names are there but the connection still times out.
