Connect/disconnect from VPN makes Outlook 2007 hang forever

[Tim Zych]

Outlook 2007, using Exchange.

I launch OL 2007 and am connected to my cable internet.

THEN I VPN to my client, and Outlook 2007 "hangs", displays an hourglass and
never regains consciousness. I think once it regained consciousness after
several minutes during the many times I have tried this. Other times it took
so long that I terminated the app.

This does not happen at all with Outlook 2003 (different machine, same
configuration AFAIK). Outlook 2003 works perfectly and quickly.

Alternatively, once I am connect to the VPN, THEN OPEN Outlook, it's OK
(slow as hell, but works). Then I disconnect from the VPN, it freezes,.

Surely there must be a setting I have not set. Outlook 2007 cannot be this
unusable(?). I must be missing a configuration option?

Someone gave me an MTU registry fix which I tried, but that didn't help at
all.

Thanks for any ideas.

Problem solved. I checked "Use Cached Exchange Mode" in the Advanced tab of
the Account options and that fixed both of the problems: The VPN / LAN
switching issue as well as the abysmally slow Outlook issue.
