That usually means something is blocking the traffic - a firewall is the usual culprit.

Exchange/Outlook communication is actually push. Exchange tells Outlook something has changed and then Outlook will go and look. If that push packet is blocked then Outlook doesn't know anything has changed and will only look when the user needs to use a different view which requires a refresh.

Therefore you need to look at the clients and the server to see if a firewall is blocking the traffic - perhaps there was an exclusion on there before for a specific IP address of the old server, something like that.



I have only 4 client servers ( 4 Citrix running server 2003 ) whith 100 users.

My laptop running windows vista an office 2007 has no problem

the firewall service on the citrix server is disabled.

then i have a ole windows XP in a VM-ware player, running a outlook 2003, and i have the same problem...

so i have only 6 serveres
1 file server (server 2003)
1 exchange (server 2008/exchange 2007)
4 citrix (server 2003 /outlook 2003)

and then all users connect to the citrix for accessing outlook.


If i log into my server as administrator, i dont have the problem
I deteleted the mail configuration on a test user, og setup the exchange agin - but i stil have the problem

Is the laptop without an issue running in cached mode?
Cached mode works in a slightly different way to Outlook live. As you cannot run cached mode on Terminal Servers you may well be using Outlook in two different ways.

Have you run the best practises tool from the Toolbox?


In Outlook, Check bottom right hand of window to see if it states Connected to Microsoft Exchange.

If not Right click on it and see if Work Offline is checked,  If it, is turn it off


All users are working online.
I had the same problem on my laptop running a windows XP on a virtual PC but if i run outlook in cached mode, et seams to work.

The best practises tool from the Toolbox i had a error:
The registry value 'TcpTimedWaitDelay' on registry key 'System\CurrentControlSet\Services\Tcpip\Parameters' is not currently set to 60. This may cause connection problems for clients using this server.

on my server the setting is: 4294967295 - but if I change it to 60 - i can´t receive any mail.

Did you change that setting?
Are the NIC drivers fully up to date?


I got a roolup 6 for exchange 2007 from Microsoft support and that fixed my problem.
