New Email doesn't appear until I change folders

P

PR

A recent automatic Windows update created a glitch in my Outlook (this is not
the first time). New e-mails do not appear until I open my Outlook and click
in any other folder (other than Inbox). Once I look at any other folder, all
the e-mails that I have received suddenly show up (some hours old, if I have
not remembered to check frequently).

Our office tech support guy showed me how to fix this once (a long time ago)
but I can't remember how to do it and I can not contact him now. I think it
was a security setting - something like Outlook needing to be added to a list
of "allowable" programs or something.

While I realize this might not be an Outlook glitch (might have to do with
our office security), it was something caused by a Windows update, so it does
pertain to Windows.....

Anyone have any ideas?

If you're running Windows XP, it could be that you have to add Outlook.exe to
the Windows Firewall.
If you connect to an Exchange server that is external to your domain, it
could be an issue with UDP packets and how they are handled through the
router.
You would need to provide more details such as Outlook version, O/S version,
what type of email environment you're in (POP3, Exchange, etc.), any error
messages, any entries into your application event viewer, etc. to
troubleshoot this.

Are you connecting to an Exchange server?

This sounds like a UDP issue. This issue occurs because Outlook uses the user
datagram protocol (UDP) to receive new e-mail message notifications, to
update folder views, and to perform searches.

When making an initial connection to an Exchange server, Outlook registers
itself for new message notifications. Whenever a new message is received in
an Outlook user's mailbox, Exchange sends a notification to Outlook using
UDP. This notification is essentially a small flag to the client that a new
message is present and needs to be displayed. When Outlook receives the UDP
notification, it retrieves the message from the Exchange server and displays
it in the appropriate folder (e.g., the Inbox).

New message notifications are intended for Outlook clients that are running
in either online mode or Cached Exchange Mode, and they won't work for
Outlook clients using RPC over HTTPS. In fact, when using RPC over HTTPS,
Outlook does not register for notifications (because it won't be able to
receive them). Instead, Outlook clients using RPC over HTTPS use a polling
mechanism to check for new messages. While polling is initiated by Outlook,
the polling frequency is dictated by the Exchange server. Polling is not new
to Outlook 2003; Outlook 2002 automatically reverts to polling if the UDP
notification fails. However, new in Exchange 2003 is your ability to
configure a polling interval for RPC over HTTPS clients.

Is the Windows Firewall turned on? You may need to create an exception to
allow Outlook traffic. Is the problem with Outlook the same in cached mode vs
not cached mode?

Exchange 2003 - Outlook 2003 online mode. Windows Firewall disabled..

This is only happening on XP machines. I have mostly 2K workstations and they work fine. I just put a handful of XP machines up and they all show this issue.

I get the envelope flag in the tray but the messages don't show up until I switch folders.....
