Outlook 2007 on Windows 7: Always exactly ONE message stuck in Outbox

We are using Exchange 2007 SP1 and Outlook 2007 SP2. Most computers run on Windows XP, a few run on Windows 7.

A portion of the Windows 7 machines has the problem that always exactly ONE message is stuck in the Outbox. So, if Outbox is empty and the user sends a message, it remains in the Outbox. If he opens it from the Outbox and clicks "Send", it gets italic for a second and then is changed to normal font again and stays there.

As long as this one message is stuck there, the user can send all other messages. All mails are delivered perfectly. However, when he deletes this one stuck message, the next message will be stuck.

It would be a "workaround" to have always one stuck message there, but that can't be the real solution =) ... Does anyone have an idea on this issue?

The problem appears on 3 of about 20 Windows 7 computers, but on NONE of around 2000 Windows XP computers. The users are using Outlook Cache Mode.

What anti-virus software are you using? Do you have any 3rd party firewalls installed? How are they connecting to the Exchange server - locally or via Outlook Anywhere or ?

Anti-Virus software is Symantec Endpoint Protection 11.0 MR5, however without the E-Mail/Outlook Add-In. There are no other firewalls installed, and Windows Firewall is turned off for the domain network.

The users are connecting to Exchange locally.

BTW, it seems that creating a new OST file solves the problem for a while, but then it reappears. And I forgot to mention that we use Enterprise Vault 7.5 SP4.

Hi,

If you use OWA, will one message be stuck in the outbox?

Did you try to delete the outlook profile and create a new one?

Control panel->Mail->Show profiles...->Remove

And if Windows 7 user log on to Windows XP client, same error?

Sorry, I overlooked your reply (likely notification landed in Spam folder)

With OWA, the problem does not appear.

I tried to delete the profile and create a new one. This seems to help for a while, but then the problem re-appears.

All those users had Windows XP before, and the problem did not occur. When the user logs on to a Windows 2003 terminal server and uses Outlook there, it also does not appear. It seems to be related to the machines, not the mailboxes or user accounts.

The problem still persists, does anyone have an idea?
