We had suspicions that it was the UDP packets however, this occurs randomly and in my case it's throughout the company. Not just on one subnet. There is no router or firewall just a switch. Considering it happens randomly, I think the switch isn't the problem here. We used a product from NetIQ called Queue check and verified the udp packets are getting through just fine. Of course this is random so??? At any rate do you think it is possible that the Exchange server is not sending the UDP packet? I'm pretty sure it's the network, however one of the guys here asked me to post the question.

I would be on a network problem. Have you checked the NIC settings? If it is on a switch try setting to 100mb/full duplex. Make sure that the Exchange server is on a switch and can be set to 100mb/full duplex as well. Are there any routers between the clients and server? It sounds like it since they are on different subnets. New mail notifications are sent as UDP packets. If you have routers or a firewall that is blocking UDP, then this will cause the behavior you are seeing. I would check those rather than lay the blame on the clients.

What happens is when you startup in the morning mail comes in fine. Throughout the day, Outlook will be running in the background and you will not get any mail. As soon as you click on something in Outlook... BAM! 3-4 messages arrive all at once. -----Original Message----- From: Bowles, John L.

They should just be getting their email when it comes in. You said that they are "Pulling" their mail in. If it's setup in the Corporate environment then they should receive their mail in real time. Maybe i'm not reading something right here. Let me know. ___________________ John Bowles Exchange Administrator Enterprise Support & Engineering Celera Genomics [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> -----Original Message----- From: Sandoval, LaCretia, Triaton/US [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 31, 2002 10:56 AM To: Exchange Discussions Subject: RE: Outlook won't bring in mail In my environment we are setup in a Corporate environment. -----Original Message----- From: Bowles, John L.

Seems like if they click in outlook all of the sudden several messages appear at once. ??? Let me know if you figure it out.

Client : Win2k Outlook 2000 Server: Exchange 5.5 NT 4 SP 6a I have exchange and some clients sitting in one subnet (say 10.0.0.whatever) and clients sitting in another (say 192.168.20.whatever). Clients in the exchange subnet get their mail just fine, however clients in in the 192 subnet have a difficult time getting outlook to bring in their mail in a regular fashion. When they start outlook up, it connects to exchange and pulls all of their mail in, but here is were it gets weird. If outlook is the only running application, it will continue to bring mail in, however if other applications are being run, and outlook goes to the background, the only way that the client can bring in their mail is to click on their inbox or hit send and rec. I've never seen this happen before, and tweaks that I've done to the settings in outlook don't seem to fix anything. Thoughts?
