Outlook disconnects from Exchange every 10 seconds in RPC over HTTP mode
Posted on 2012-12-27
Hello, i am having some problems with Outlook 2010 running in RPC over HTTP encapsulation mode on my Windows 2008r2 Remote Desktop server. It is currently connecting to a Exchange 2013 RTM server, but it also had this same behavior connecting to an Exchange 2010 sp2 server as well. About every 10 seconds, it disconnects and then immediately reconnects. When it does this, i see event 26 logged in the event log. It does not have this problem at all in MAPI mode. Other computers do not seem to have this problem either. I had configured all the clients that connect to this server via remote desktop to use MAPI protocol, and this worked great without issues. However, with the release of Exchange 2013 this is no longer an option. I have tried to disable RSS, chimney offload, and netdma settings on the nic, but this did not help. Thank you in advance for any insight you may have.
