OL2007B2 - Cannot Connect To Exchange Through VPN
Ok, here is the setup:
Laptop w/ Windows XP SP2 + All patches. Running clean Office 2007 B2. Not connected to the LAN, through a cable modem with Netscreen client version 8.7: Fired up Outlook 2007, setup profile, do a manual configure, select "exchange", then type in server name and mailbox name, clikc on "Check"... gets an error: An unknown error occurred, error code: 0x90040605 If I connect to the LAN, works. If I connecct wirelessly, works. Ok, so once connected to the LAN and get it to recognize the mailbox and get Outlook configured properly, I am now remote. Connect VPN through Netscreen client. Fireup Outlook... It can never connect to the exchange server. Frustrated, I uninstall Office 2007 Beta, go back to Office 2003 Pro, set it all up and all works through the VPN flawlessly. Including setting up Outlook profiles and such. So, it seems Outlook 2007B2 is having a problem with VPN connections. We tested this with the Cisco VPN client and is having the same problem there, too. When you look at traffic on the PC, it doesn't even try to send it out the VPN tunnel. Any ideas? Very strange, as Outlook 2003 didn't care what connection you had it on, as long as it had a connection. Jonathan Merrill MCP, CCA, NET+ www.gomerrill.com

OL2007B2 - Cannot Connect To Exchange Through VPN
How our network is setup is once you VPN, you can access all ports to any of
our servers. Further, the mail server is not locked down or has any security templates applied to it. This is a test environment. And we use Exchange 2003, all patches, all service packs. Appreciate the response. Outlook 2003 works no sweat under this configuration, so I am leaning on OL2007B2 having a problem with VPN tunnels. Anyone else test OL2007B2 through their VPN client? J.

OL2007B2 - Cannot Connect To Exchange Through VPN
No, the VPN connection is on another non-routable subnet. This allows us to
log any traffic on that particular subnet coming into our test network. So, the VPN user subnet would be on a 172.16.x.x. The test server network is 192.168.x.x. Also, tested this scenario with the Watchguard VPN client, and it also does not work. Appreciate it!

OL2007B2 - Cannot Connect To Exchange Through VPN
No, not possible. But the curious portion is why Outlook 2003 works
unhindered. This issue only presents itself with OL2007B2. Also, we are running a sniffer and do not see any packets coming from the laptop to the exchange server, beyond the usual traffic.

OL2007B2 - Cannot Connect To Exchange Through VPN
Appreciate your help.
Looking at the sniffer traffic between the subnets, it appears the laptop is not sending any traffic to the exchange box other than the usual NETBIOS stuff. Upon hitting "Check" when setting up the profile to looking up a mailbox, you'd normally see a bit of activity. In this case, tested with three VPN clients on two different laptops (Dell Latitude D600 and HP Compaq nc6220 laptop) all running Windows XP SP2 (Build 2600.xpsp_sp2_gdr.050301-1519 : Service Pack 2). None of these test laptops run the XP firewall. No activity across the tunnel from Outlook. I can ping the exchange server, I can browse files across the tunnel, and can web browse our intranet. I can open up OWA across the tunnel. Thanks again, Jonathan Merrill MCP, CCA, NET+ www.gomerrill.com "Roady [MVP]" wrote: Can you see at what point they are being dropped? Client level or later?

Appreciate your help. Looking at the sniffer traffic between the subnets, it appears the laptop is not sending any traffic to the exchange box other than the usual NETBIOS stuff. Upon hitting "Check" when setting up the profile to looking up a mailbox, you'd normally see a bit of activity. In this case, tested with three VPN clients on two different laptops (Dell Latitude D600 and HP Compaq nc6220 laptop) all running Windows XP SP2 (Build 2600.xpsp_sp2_gdr.050301-1519 : Service Pack 2). None of these test laptops run the XP firewall. No activity across the tunnel from Outlook. I can ping the exchange server, I can browse files across the tunnel, and can web browse our intranet. I can open up OWA across the tunnel. Thanks again, Jonathan Merrill MCP, CCA, NET+ www.gomerrill.com "Roady [MVP]" wrote: Can you see at what point they are being dropped? Client level or later? No clientside firewall that could block the traffic? VPN to an Exchange server on the same network as an Outlook 2007B2 client has been verified to work. Still waiting for results for when they are not on the same network. -- Robert Sparnaaij [MVP-Outlook] Coauthor, Configuring Microsoft Outlook 2003 http://www.howto-outlook.com/ Outlook FAQ, HowTo, Downloads, Add-Ins and more ----- "Jonathan Merrill" wrote in message ... No, not possible. But the curious portion is why Outlook 2003 works unhindered. This issue only presents itself with OL2007B2. Also, we are running a sniffer and do not see any packets coming from the laptop to the exchange server, beyond the usual traffic.

No, the VPN connection is on another non-routable subnet. This allows us to log any traffic on that particular subnet coming into our test network. So, the VPN user subnet would be on a 172.16.x.x. The test server network is 192.168.x.x. Also, tested this scenario with the Watchguard VPN client, and it also does not work. Appreciate it!

As an additional question; is the VPN client located on the same subnet as the Exchange server? -- Robert Sparnaaij [MVP-Outlook] Coauthor, Configuring Microsoft Outlook 2003 http://www.howto-outlook.com/ Outlook FAQ, HowTo, Downloads, Add-Ins and more ----- "Jonathan Merrill" wrote in message news
How our network is setup is once you VPN, you can access all ports toany of our servers. Further, the mail server is not locked down or has any security templates applied to it. This is a test environment. And we use Exchange 2003, all patches, all service packs. Appreciate the response. Outlook 2003 works no sweat under this configuration, so I am leaning on OL2007B2 having a problem with VPN tunnels. Anyone else test OL2007B2 through their VPN client? J.

Another one; what version of Exchange is running? Outlook 2007 cannot connect to Exchange 5.5 and previous. -- Robert Sparnaaij [MVP-Outlook] Coauthor, Configuring Microsoft Outlook 2003 http://www.howto-outlook.com/ Outlook FAQ, HowTo, Downloads, Add-Ins and more ----- "Jonathan Merrill" wrote in message ... Ok, here is the setup: Laptop w/ Windows XP SP2 + All patches. Running clean Office 2007 B2. Not connected to the LAN, through a cable modem with Netscreen client version 8.7: Fired up Outlook 2007, setup profile, do a manual configure, select "exchange", then type in server name and mailbox name, clikc on "Check"... gets an error: An unknown error occurred, error code: 0x90040605 If I connect to the LAN, works. If I connecct wirelessly, works. Ok, so once connected to the LAN and get it to recognize the mailbox and get Outlook configured properly, I am now remote. Connect VPN through Netscreen client. Fireup Outlook... It can never connect to the exchange server. Frustrated, I uninstall Office 2007 Beta, go back to Office 2003 Pro, set it all up and all works through the VPN flawlessly. Including setting up Outlook profiles and such. So, it seems Outlook 2007B2 is having a problem with VPN connections. We tested this with the Cisco VPN client and is having the same problem there, too. When you look at traffic on the PC, it doesn't even try to send it out the VPN tunnel. Any ideas? Very strange, as Outlook 2003 didn't care what connection you had it on, as long as it had a connection. Jonathan Merrill MCP, CCA, NET+ www.gomerrill.com
