First of all I have read the other posts on this subject but I'm still having issues with OA working on XP clients.
Exchange 2010 SP2 RU5v2
4 Cas/HT servers behind a citrix netscaler, created a cas array
4 Mailbox Servers
1 Cert from Thawte using SAN names
Subject: webmail.domain.com
SAN Names: autodiscover.domain.com, casarray.domain.com, casserver1.domain.com, casserver2.domain.com, casserver3.domain.com, casserver4.domain.com, netscaler1.domain.com, netscaler2.domain.com, webmail.domain.com
When I run: get-outlookanywhere | fl
All 4 of my cas server shows:
ExternalHostname: webmail.domain.com
ClientAuthenticationMethod Basic
IISAuthenticationMethods {Basic}
Currently I have the outlook provider expr set to "none" via:
Set-OutlookProvider EXPR –CertPrincipalName none
I have tried setting it to "webmail.domain.com" via:
Set-OutlookProvider EXPR –CertPrincipalName msstd:webmail.domain.com - That still didn't work.
So I put it back to and currently have it set as:
Set-OutlookProvider EXPR –CertPrincipalName none
At this point OA on XP sits there stating trying to connect but eventually fails.
Also to note we are going through ISA 2006 as a proxy (cert on proxy server), then going to the VIP of the Netscaler, which is set to SSL Offload and our cert is bound to the netscaler vip.
Please help.
