Why won’t Outlook 2007 send mail from the outbox?
Question by leonard rosen /

I am using Outlook 2007 & Vista and I am having trouble sending email. I click on compose a message, write my message, click on send (there is no attachment) and the message goes into the outbox.

For some reason, messages won’t send from the outbox which has happened quite a lot. I downloaded free software called ReliefJet Essentials to try to correct the problem but it did nothing.

Why are messages staying in outbox when there are no attachments. In both cases they were messages forwarded which had been send by someone else.

    Is this happening with all messages or only a few? Are your settings for your outbound email correct? Try to send a test message from the email account settings page.
