Jun 11, 2012OWA Proxying in Mixed Exchange 2007&2010 Environement
We're new to the F5s. We've configured F5s in front of our Exch 2010 CAS Servers.
Here is our setup:
1- SITE A: 2x Exch 2010 CAS Servers behind F5s and 1 Exch 2007 CAS . Exch 2010 & Exch 2007 MBX Servers.
2- SITE B: 1 Exch 2007 CAS Server and 1 Exch 2007 MBX Server.
When access Exch 2010 mailbox in Site A through the F5s everything works fine.
When accessing Exch 2007 mailbox in Site A through F5s, the redirect works fine and use is able to access their Exch2007 mailbox.
When accessing Exch 2007 mailbox in Site B through F5s in Site A. Exch 2010 CAS proxies the connection to the Exch2007 MBX Servers in Site B and OWA page take very long before it loads and it loads with errors. None of the links are usable or clickable. completely unusable.
The tests above have been done using IE without checking "User the light version of Outlook Web app"
When using the Light version of outlook web app with IE or using firefox or Chrome, OWA site for Exch 2007 mailbox in Site B comes up just fine and proxying works as intended.
Tested Proxying using Full OWA on IE bypassing the F5s on Site A to access an Exch2007 MBX in SiteB and it also works fine.
The issue is with accessing Exch 2007 Mailbox in a secondary site through Proxying from Exch2010 server that's behing an F5 load balancer.
Anybody ran to any similar issues, any suggestions ideas are much appreciated.
Thanks.
