Exchange 2007 + Outlook 2007 + Wndows PPTP VPN = can't connect to exchange server

Hi Guys,

Outlook cannot connect to exchange server [from home] while I'm connected using VPN.
I can ping the server. Outlook is the using cache mode. Exchange 2007 SP1.
Exchange 2007 has a pretty default config, new installation so I must be missing some config.

Many thanks for your help.

Regards,
Pawel

startup outlook.exe /rpcdiag to see where it goes wrong.
also check the event viewer and post any relevant errors / warnings.
sounds to me that ipmc is working but rpc might not get through.
are you using outlook everywhere?

Hi,

Have you spent a while trying to get Outlook 2007 to connect to your Exchange Server over a VPN connection, yet when on the LAN it works immediately&and with 2003 it was fine? Me too& Assuming you have checked the obvious (VPN connection is good, routing is ok, you can access other parts of the LAN over VPN etc)

The simple answer -

"Outlook 2007 uses the fully qualified domain name of your server
"mailserver.ourdomain.com not simply the server name mailserver
"Your hosts file probably only has the server name
"10.10.12.200   mailserver
"Add the FQDN to your hosts file
"10.10.12.200   mailserver.ourdomain.com
That should correct the problem of Outlook 2007 not connecting to Exchange Server over VPN.

Hi,

I'm not using Outlook Anywhere and I've tried the host file. It didn't work.
Will try outlook.exe /rpcdiag now.
Thanks.

I've tried outlook.exe /rpcdiag it says "server.domain.local connecting" and then that msg disappears.  I cannot see anything unusual in the logs.

Hi,

One more thing to look at is to disable IPV6 if you have enabled it!

Hi,

Do you have all the latest patches of Outlook installed from Microsoft update site? also check event log and see if you find any specific error there.

It is the hosts file. However, to see what it's looking for look at the Exchange server entry in the outlook profile and see what the server is listed as. Then put corresponding entry in the hosts file with the correct IP address.

Also - just as a check, the two sets of IP range aren't the same at the office and the remote LAN (ie if they're both 192.168.1.x then no traffic will go across the pptp as the router will be very confused.)

Hi,

I've tried the host file. It doesn't work. IP connectivity is OK.
Do you know what makes Exchange2007 so "special" about the configuration.
I didn't have that problem with Exchange 2003.
Any ideas?
