Helping people with computers... one answer at a time.

Once a message goes into your outbox, Outlook tries to send it. While it's trying, there's little you can do. So the trick is to force it to stop trying.

How can I stop, delete or move an email that gets stuck in my outbox? The email I have here is 24.5 MB, which is apparently too big. The problem is that it's stopping all my other emails that I want to send from going out! I use Microsoft Outlook 2003.

It's been a while, but I've experienced this myself. Your ISP rejects the email because it's too big, only to have Outlook keep trying to send the mail because it doesn't realize that the error is fatal.

There are a couple of ways to deal with this issue. Surprisingly, the most low-tech solution is what I've found to be the most effective.

Let's say your ISP has a cap of five megabytes on email message size. You start sending your 24.5 megabyte behemoth, and five megabytes in your ISP's mailer says "Nope, too big - FAIL".

Outlook doesn't realize that that's not going to get fixed and treats it like any transient error that might not happen if it tries again. So it tries again. And again. And again.

With no actual hope of success.

Meanwhile, once you realize that there's a problem, you can't do anything about it, because Outlook has the message while it's trying to send it. You can't delete or move an email that Outlook is in the process of sending.

There are two ways I've approached this problem in the past:

Get lucky - there's a small window of time between the failure and Outlook's next attempt to send it when it does not have the message locked. If you're lucky you can delete it during this time. But you must be really lucky.

"Outlook doesn't realize that that's not going to get fixed, and treats it like any transient error that might not happen if it tries again. So it tries again."

Pull the plug - not the power, but your network. Literally disconnect yourself from your network. Outlook will not be able to contact your ISPs server at all and won't even begin to try sending your message. It might take Outlook a few seconds to realize that it's off line, but once it does, you can delete or move the message. After that, reconnect to your network and get on with your lifeemail.

It's decidedly low-tech, and I can think of a few other ways to accomplish the same thing, but ultimately it's simple and fast and achieves the desired results.

Microsoft recommended various complex and time-consuming solutions, but you nailed it.

Even Easier Solution: Click "Cancel Send/Receive". Then Right-Click the troublesome email and select Delete. Problem solved.
