Microsoft Outlook 2003 sending messages, but they show stuck in Outbox

Posted on 2009-04-24

We have a client who just had his computer wiped clean and everything reinstalled. Everything was working fine, until today. He has ACT 2008 installed using Outlook 2003 as its email client. If he originates a message in Outlook, it sends without issue. If he replies to a message, or originates a message via ACT, then the messages get sent, but they stay in the Outlook Outbox.

I have been able to replicate this 100%. Messages started from scratch work fine. Replies to messages I email in to him are a problem.

I am currently checking for Office/Microsoft/Windows updates, but ACT 2008 is up-to-date. The reason I mention ACT in a couple of spots is that it has installed its software agents inside Outlook to allow him to attach contacts and email to the ACT contacts.

Any ideas where else to troubleshoot?

    GLComputing: This is close, but as I mention, the messages get sent through Outlook even though they show they are stuck in the Outbox. I have seen the problem shown in that Sage ACT KB article, but in this case, that solution does not work.

    Another other ideas? This is an odd one!

    Accepted Solution

    I created a workaround, or discovered that the problem is a corrupt Outlook profile:

    I created a new Outlook profile, then imported all data from the previous Outlook PST. I reset the ACT email settings to Outlook Express temporarily while creating the new Outlook profile. Once the new profile was complete, I switched the ACT email preferences back to Outlook. Started up Outlook and I can reply to messages without messages sending and simultaneously getting stuck in the Outbox.

    It appears that the connection between ACT and Outlook somehow corrupted the Outlook profile. We haven't had this problem before with numerous ACT/Outlook users, so I have to figure it was an isolated issue.
