VPN user unable to use Cached Exchange Mode while on VPN
Shortly after a recent upgrade from a Sonicwall TZ 170 to a TZ 190 (w/latest firmware) I have 1 user who is unable to update his Outlook 2003 mailbox while using Cached Exchange Mode to the Exchange Server 2003 SP2 server over the VPN.
I dd receive a single instance of event ID 9646 for exceeding the maximum of 32 objects of type "session" for this user. I proceeded to increase the maximum on the server to 64 without any change.
If I turn off the cached mode, Outlook works fine, but has the typical delays associated with not using Cached mode.
For whatever reason, when I do a send/receive command it says it works fine, but the in the lower right corner the mailbox indicates is was last updated 2 days ago and none of the current mail shows with the cached mode on.
FYI - The user in question has a 2.8GB mailbox....all the other users are 1GB or less, but it worked fine until recently.
I hope this helps or gives you some ideas...
