Hi,

A couple of days ago my Live Mail account started giving me 3219 error whenever I tried to send or receive emails. I'd read that enabling POP via outlook.com could fix this, so added a new Live Mail account with the same email address using altered settings and am now able to receive emails, but not send them.
These are the current settings:

Incoming mail: POP3 server
Incoming mail (POP3): pop-mail.outlook.com (port 995)
Outgoing mail (SMTP): smtp-mail.outlook.com (port 25)
SSL conenction is enabled for both options.

Whenever I try to send an email from this account I get the following error message:

"The message could not be sent because the server rejected the sender's email address.

Server error: 550
Server Response: 550 5.7.3 Requested action aborted; user not authenticated.
Windows Live Mail Error ID: 0x800CCC78
It looks like the outgoing mail server's settings are wrong but I don't know what to change them to. Any help would be greatly appreciated.

Wixi my suggestion is to try Thunderbird - I have both set up (I can swap between the two) and I still have it set up with my two email accounts and configured to look like WLM see pic
The choice of course is yours but I find it as good as WLM just it takes a while to download your emails from the accounts you use.

Hi ICIT2LOL, thanks for the advice. :)

I'd been hoping there was a way of getting the Live Mail account working again, but if not I'll give Thunderbird a try.
