To get better clarity on the issue please answer the questions below;

  1. What is the current version of Windows Live Mail installed on your PC?
  2. What is the current operating system installed on your PC?
  3. Did you made any recent changes to your PC?
  4. Do you face the similar issue when you access your account through web browser?
  5. Do you get any error message when you try to send an email?

Please get back to us with the above information so that we can assist you further.

I have the same problem as William Conti and my answers to Juzar_Ali's questions are as follows.

1. Windows Live Mail 2012.

2. Windows 7

3. No changes have been made to my PC or my wife's PC. (she is having same problem)

4. Access through web browser appears to work.

5. " The message could not be sent

      the settings on your outgoing email(SMTP) server may need to be reconfigured

      please contact your email server provider

      server error 450

      server response 450 4.4.0 relaying temporally denied

      cannot resolve PTR

      server: mail.TPG.com.au

       windows live mail error id: Ox800ccc79

       Protocol: SMTP"

I sent a copy of error message to email server provider (tpg.com.au) who suggested that I contact Windows Live Mail Support Team.

Could you please help?

Thank you for your reply.

The problem now appears to be fixed.

I removed all messages from the outbox & found there were a few Windows updates that had not been processed.

I then processed all the Windows updates that had not been processed & managed to send test emails to my wife & daughter without encounting any errors.

thank you

Robert

You left out some important bits of the error message. It's always best to copy and paste error messages to ensure that everything is included and there are no typos. You can click on an error message to select it, then use right-click to copy it and paste it into the text entry box.

SMTP error codes starting with 4 (450 4.4.4) indicate temporary errors. If you're seeing this with every message you try and send over a period of days, there's probably something not right with your settings. Please remove any unsent messages from the outbox (below the account folders in the folder pane), then compose a new test message with a unique subject and send it to yourself (i.e. from the tpg.com.au account to the same account). Post any new error message in your reply.
