Outlook outbox will not complete sending

[Wayne Brown]

OS: XP SP2
Problem started on 9/21/07 using Outlook 2003. Upgraded to Outlook 2007,
same problem.
When sending a new message or forwarding a message to another address,
message goes to outbox and will not finish sending. Eventually get
0x8004210b error.

Set up new user account, tested settings, sends test message okay and it is
received. New and forwarded messages get stuck in outbox.

Sent message to this computer from outside requesting read receipt. Read
receipt is accepted and sends out receipt okay.

Installed Outlook Express 6, it works fine and is what I am on to send this.

Set up new account for user on another computer on network using Outlook
2003. Works fine.

Turned off firewall and uninstalled AVG free so currently have no antivirus
or firewall active.

I can delete messages in the outbox in offline mode, switch to online, and
send receive reports completion okay until I try to send or forward a
message.

Problem seems to be specifically isolated to this computer and to Outlook.
Ideas? Thanks

This afternoon I got this error message for the first time although I had
sent e-mail this morning. I came across another forum and was happy to see
there might be a way to solve the problem by changing port 25 to 587. I did
this and tried to send my mail again. No luck.

Here is the funny thing. I have 3 e-mail accounts all from the same
provider. All 3 accounts are set up exactly the same with only the e-mail
address and passwords being different. I tried sending out one of the e-mails
in my outbox using the second account and it worked fine. I then tried
sending out another e-mail in my outbox using the third account. Again, no
problems. When I checked I my settings for the "bad" account, I did a test of
account settings. It showed no problems and I in fact received the test
message.

Hmmm, now what to do. The test message proved there was not a server problem
as did the 2 e-mails I sent using the other 2 accounts. I tried shutting down
Outlook 2003 and re-opening it. Still no luck. I was not about to get into
re-installing Outlook. So what I did was to delete the "bad" account and then
add it back. Lo and behold, the problem was resolved as I could now send
e-mail from this account.

From the time I sent e-mails this morning until I ran into this problem I
made no changes to my computer. I have none of the programs Microsoft blames
this problem on. So what the hell happened? Well I do not know but hopefully
this thread can stay alive long enough for someone to enlighten us about this
glitch. The fact that only one account was affected and only for mail sent
from the outbox (account settings test message worked fine) baffles me.

Try deleting the affected account, reboot and then add the account back in.
Although it sounds like you tried deleting and re-adding the account, maybe a
reboot will help.
