ASA5510 WebVPN & Outlook Web Access attachment problem

[ewong0088]

Any help and/or pointer to solve this problem is greatly appreciated.

Running ASA5520 WEBVPN with OWA with OWA published. Normally it works fine. Sending/receiving emails work. However, if any emails contain attachments AND the attachments is (haven't done them all yet) greater than a certain size, saving(download) the attachment will not work, return with error "Server time out". If just try to download small files(I've tried to download something from 10K up to 30K, without problem) I know for sure that anything greater than 1MB will not download. Caching is truned OFF, same behavior.

Any idea?

Thanks.
