Outlook: Mensagens trancadas na caixa de saída

3 12 2008

Hoje vi um problema bem curioso. Uma estação com outlook 2003 client de um exchange 2003 e um usuário reportando o seguinte:

Ao enviar e-mails, algumas mensagens ficam na caixa de saída, e não são entregues ao destinatário. Os endereços estão corretos, e realmente eu confirmei que os destinatários estão ok. O problema ocorre aleatoriamente, mas a maioria das mensagens enviadas são entregues.

Como eu nunca tinha visto isso tive que ir para o support da microsoft e google, e terminei achando o link abaixo:

Segue um trecho:

If you click on the Outbox while messages are waiting to be sent, the messages are marked as read and won’t send.

This is caused by a Net framework add-in you have installed that ‘reads’ Outlook items, including the Send to OneNote from Outlook PowerToy add-in and BCM (Business Contact Manager). A list of other add-ins known to cause this behavior is listed below.

To send the affected messages, you’ll need to open the message, then switch to a different folder before clicking Send on the message. Do not go open the Outbox until after the messages are sent.
To identify the add-in that results in this behavior:

Look in Tools, Options, Other, Advanced, Com add-ins. Disable the add-ins and re-enable them one at a time and test.

Since BCM and possibly other add-ins are not listed in the COM add-in list, check
# HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins
# HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins

Export the keys then change the LoadBehavior value to 0 to disconnect an add-in. Restart Outlook and test.
