Default outlook and exchange seems connected, but..

Weird and no. Is there anything between server and client that would block
UDP? (Example, if using firewall or ACLs on a router, the direction of flow
is Exchange to client. A firewall rule would read source port ANY to
destination port =1024.) By the way, don't forget to look at QoS. Usually
UDP is the first to get dropped when the network link gets busy.

hello,
we have cached mode used and we are connected via RPC/TCP. Should I try
to switch cached mode off?
Thank you very much for replies.

Interesting, Outlook 2003/7 should switch to polling the Exchange server
when the UDP packets don't make it from server to client. Since you
mentioned "connected", I'll assume cached mode is being used. Connecting
to Exchange via RPC/TCP or RPC/HTTPS?

You don't mention what version of Outlook you are using, but with older
versions (Outlook 97 thru 2002) a personal firewall could interfere
with receiving new items. The reason why is that the personal firewall
(e.g. Windows Firewall included in XP) will block the UDP network
packet from Exchange to the desktop informing Outlook something is new,
come check and redraw your interface accordingly. This UDP network
packet cannot be locked to any specific port.

ps - to verify the above, rather than restarting Outlook. The user
just has to switch away from Outlook's Inbox and then back to it.

November, 25th,
hello,
we have problem with emails.
Sometimes somebody, often, has problem with emails (I have mentioned
such situations before). Outlook is f.e. on desktop, notices that
connected to our exchange server. But:
no new emails are coming.
What helps? Quit outlook and check, if it can be seen in taskmanager,
kill Outlook process in taskmanager, Outlook remains there, and start
Outlook again.
To simply restart Outlook only helps not.
Can you advice us any better another solution? Thank you for help.
Best regards,
