Outlook 2011 can receive messages but cannot send

Using Outlook 2011 and have two pop accounts setup. They have been working fine all year and now only one of them cannot send email. I have verified all account settings with the host. Deleted the account information and re-entered it in again. Same result. Have rebuilt the identity. Same result. Any help is appreciated!

Try setting the port on the SMTP server to 587 if it's currently set to 25.

Port is correct and verified. Also tested port 25, 587 and 465. All the same result.

What happens when you try to send? Are there any error messages in the console logs?

I suggest you open Console.app, then try to send mail and see what error messages show up in the system log.

Hi Aks,

Is this issue only with outgoing emails? If yes, then enable the “My outgoing server (SMTP) requires authentication” option from the advanced settings.

Also, enforce the right encryption level on the outgoing server (SSL or TLS).

Feel free to respond back!!!

Thanks & Regards

The popup error message lists "5.7.0  ....authentication rejected (6)." and the console shows error code -17900.

Also all account settings are set correctly and been verified by the host. One account that points to a different host works just fine. The other account which points to another host is the one that is able to receive but not send. And all settings have been verified by both hosts.

Right now my only thoughts are to run a data backup, uninstall office 2011 and then reinstall and restore data.

Are you absolutely sure that, for the account in question, you have entered the password correctly for both the POP server and the SMTP server?

Uninstalling and reinstalling seems like a pretty radical solution.
Before doing that, I'd try changing the password for the email account on the server, and then changing it on the iPhone to match.

Yes, because same password for receiving mail which is working and whether you use the setting use the same credentials as incoming or if you enter it manually. Same result. Also the same user name and password work on a different device.

Is there something that can reset an SMTP connection for an account on the workstation?

It's an authentication error.  It is almost a certainty that, even if you think you have the servers spelled right, and the login and password spelled right, SSL is checked when it shouldn't be... something is wrong in those settings.

I would triple check, quadruple check, get a second set of eyes to look at, etc., the login name, the password, and the spelling on the smtp server in Outlook for the "problem child" account.

I've removed the account information and then entered it back in. Still same result. I've entered the same information on another machine and it works fine. It's something with Outlook and for that account, because one account works and one does not. I've checked the settings to make sure all spelling is correct several times. I've checked firewall information to see if it's blocked. Nothing listed in the firewall that would do that.

So after going through all of this. I contacted Comcast and had them refresh the email connectors for the account. Then we reset the password and everything worked.
