Hi, I have setup a VPN between Cisco PIX 515E and Cisco 851, everything is working well except Outlook. When I open it it takes very very long time to open, once opened it works well.

EXCHANGE 2010 (PIX515E) ---- VPN ---- (Cisco 851) OUTLOOK 2007.

Any help will be appreciated.

Is Outlook configured in cached mode? I expect Outlook connects to Exchange using an Exchange account, not PO3/IMAP4/..., right?

Not in cached mode, for security policies I wouldn't configure it in cached mode.

Yes it is an exchange account.

What's the ping delay from client to server?
There's no security reason why you shouldn't use cached mode. Cached mode is useful when operating on a LAN at 100Mb and is quite mandatory when operating over a WAN at XDSL speeds. I respect your policies. Please try only once to set an Outlook/Exchange profile using cached (performance isn't fine till cache is completed - usually takes a long time and starts first time you run Outlook). You will get a comparison and then you can decide if you should continue using non cached or switch to cached.

The security reason is to avoid desplaying emails without inserting the password, in cahced mode I saw that you can see the old emails in the inbox before you insert the password to download the new emails.
I did solve the problem by adding the hostname of the Exchange server in the "hosts" file in C:\Windows\system32\driver\etc\hosts, I put the exact name that Outlook see in the account settings --> Exchange server name field.
Thank you.
