Hi,

 

 

we had a similar issue with EXC2003K (de-centralized)mailboxes and EXC2007(centralized) mailboxes.

 

Basically CAS Servers are running at EXC2007 and have a default.asp which looks up the user via LDAP to determine the Mailbox Server version.

 

If it's a EXC2003 the user is redirected to /upn-suffix, while EXC2007 Mailbox users are redirected to /owa.

 

 

Never tried to do the LDAP stuff at the BigIP, but since we are moving RSA Authentication for the external CAS to the APM module, maybe I will take a look into this.

 

 

I'll let you know if I found a solution at the BigIP, or if this needs to be done at the CAS servers.

 

BTW: you should be able to send EXC2007 User through a EXC2010 CAS, shouldn't you? Normal hotfix/upgrade procedure for EXC is: start at CAS, then MBX...

 

 

Cheers
