MS Outlook and PIX

[sysadmin02]

I having problems with users recieving their mail. User need to click on a folder or other e-mail in order for them to receive new mail. New mail should appear into their Inbox automatically. Anyone else have this issue?

HI.

The mail notification works in the opposite direction from normal client server connection - the server sends the notification to the client.
Therefore if the server is on DMZ or something like that and cannot initiate inbound connections that is the cause.

You did not provide any details about your network in your question - should we guess it all?

Network schema and ip addressing?
pix configuration?
Outlook version and SP?
Exchange version and SP?

I think that MS has somekind of fix or workaround to let the client check for new mail instead of waiting for the notification.

Hello Yizhar, thanks for your reply. The workstations behind the Pix are in a 10.0.0.1 IP range. They are statically mapped to live IPs on the outside. We are using Outlook 2000 and Exchange 5.5 SP4. I do have the following established rule to allow mail to be recieved:

"established tcp 135 0 permitto tcp 1024-65535 permitfrom tcp 0"

I thought this would've done it, but am still experiencing the same problem.

HI.

You'll need to provide more info about the network.
Where is the server connected to?
What pix version?
More pix config..

In general, there is no need to use "established" in the pix because it is a statefull firewall.

We have the same problem when workstations have installed the 3.5 VPN client with the built-in firewall running.

HI Hardly.

In your case - check if there is an access-list on the inside interface (or the interface that the server is connected to), that might be blocking the notification from server to client.

You can also verify this using syslog messages.

I am having the same problems with users who are using Outlook 2000 and are set up as Exchange Clients. Was there ever a resolution to this?

HI.

I guess that the following registry tweak can solve the problem:
