Outlook Anywhere - BIGIP 9.4.3

I posted this in another forum on here, but I realize it probably is the wrong forum so I am reposting here with more details. Using the doc DEPLOYING F5 WITH MICROSOFT EXCHANGE SERVER 2007 we are trying to setup one pool for all three services with no WebAccelerator Outlook Web Access works on 80 and 443 but Outlook Anywhere does not. We are using SSL Offloading I have verified ALL services work if I hit the Exchange server directly and bypass the BIGIP. I have done some packet captures on the Exchange box and I am getting this message when trying to go through the bigip Here is the request Http: Request, RPC_IN_DATA /rpc/rpcproxy.dll , CL_ESTABLISH_IBP - ECHO_REQUEST, Using NTLM Authorization Here is the response Http: Response, HTTP/1.1, Status: Unauthorized, URL: Using Multiple Authentication Methods, see frame details Here is the irule when HTTP_REQUEST { if { [HTTP::header "User-Agent"] contains "MSRPC" } { persist uie [HTTP::header "Authorization"] 3600 } else { persist cookie } } I dont see that happen when I go direct to the server so I am guessing the irule might be causing the problem? We are using NTLM Authenticaiton. If anyone has some thoughts i would love to hear them.
