After I connect through VPN, then open up MSOutlook,  it keeps prompting me for password, then I keep closing and opening Outlook . Eventually MSOutlook will connect to Exchange server, this issue happens pretty much all the time with me and my users.

PS.   This is regular MSOutook, the OWA works just fine..


Any idea ?

Thanks

Since OWA works fine and since (I assume) Outlook works fine locally in the office, then the problem is not with Exchange.

1. Map a folder over VPN and open a file. My guess is that this is slow as well, and so the slowness with Outlook is just a function of VPN speed. Are you able to increase VPN speed? It can be expensive to do this, so most people just live with the slowness.

2. Have you turned on / are you using Outlook cache?  That is, are you working with a local OST file?  This can be faster. Or, are you working live?

So it is probably just slow VPN which is normal. Remember VPN typically uses the slow side of a communications link because it is frequently moving packets in the other direction.

I see this slowness a lot.

Check and see if this happens locally. I see the password prompt frequently with Hosted Exchange and it seems unavoidable in that case.

But if the local setup is fine and the prompt only occurs over VPN, then it is slow VPN.

The other thing is that Outlook can work via RPC and does not always need a VPN tunnel to connect. So your Outlook may be going around your VPN if your VPN client has split tunneling employed.

Compare to RPC over HTTP, VPN will be slow,

You can try accessing outlook by disabling the Addons (Run in safemode)

Start - > Run .-> outlook / safemode

You can try disabling Livemeeting trasport sending / receiving during the VPN access.

If Live Meeting is in Programs and Features, and if you don't use it, then uninstall it.

However that has not made any difference to Outlook performance in my experience.
