OWA 2010 Freezes when trying to access a shared mailbox
Hello,
Currently we have two F5 BIG IP 3900's deployed for our Exchange 2010 environment. We are noticing when users are using the VIP address to access another shared mailbox OWA freezes right after login, the only way to get out is to close the browser (This does NOT happen when they user OWA-Lite)
For instance users put in the following link:
https://VIPCASArray/owa/sharedmailbox@company.local/
The OWA login pages displays normally once after the user logs in the page freezes and they're stuck.
If they access the shared mailbox directly via a single CAS server in the array, the page loads fine, which is pushing me in the direction of a configuration issue with the F5 device.
https://CASSERVER1/owa/sharedmailbox@company.local/
This works just fine.. I did some searching around on the forums and found this article:

I removed "Keep Accept-Encoding" from the HTTP profile but the issue still occurs, if anyone has some thoughts on this issue it would be greatly appreciated.

- mikeshimkus_111Historic F5 AccountHi Anthony, this only happens when opening a shared mailbox, not the user's own mailbox? I just tried to replicate this but was unable to. Does it still happen if you remove all but one CAS server from the LTM pool?
- Anthony_VentimiNimbostratusHey Mike,
- mikeshimkus_111Historic F5 AccountOK. Also, make sure that you are using the latest version of the deployment guide, located here:

I have done serveral F5 LTM and Exchange 2010 configurations. Same problem everywhere with OWA freeze. Solved the problem by removing the Web Acceleration Profile that iApp creates on the VS with OWA.
- Perry_70844NimbostratusBjarne is correct, try disabling Web Acceleration. I'm running a pair of 3900s on 11.1 with iApp template "f5.microsoft_exchange_2010_cas.2012_06_08". Here's what I had to do with the assistance of support:
