I get this error when I have sent e-mails from outllook express No server error 553 invalid address syntax?

Question

0x800CCC79. I have checked pop3 and smtp.They are ok so why does this message occur.Sometimes messages aren't being sent from outbox. People saying they are getting the same message several times so why does it say there are messages in your outbox do you want them sent. so I click yes and people are getting several messages.

What do I do as Ive followed instructions and looked under tools,accounts etc but am still getting error messages.

Answer 1

I had a anti virus program that scanned emails, and produced this error until I turned it off. Hope this is the problem. Chow

Answer 2

I guess the unsent messages you have in your mail box are some of the messages you sent before - whenever you finish using your outlook and this message appears as you are trying to log of just click ''do not send this message'' i am quite sure you will be fine

Answer 3

Outlook will only support a couple of web-based e-mail accounts (hotmail, yahoo I think) and you have to pay around £15 for the pleasure. You might have to log into your account via the web and input some text (this is to prove that you are not a bot. Log off mail on the web and try outlook again.

Answer 4

On the servers tab,underneath your Pop settings which you say are OK .Is the box ticked that says my server requires authentication.If it isn't tick it and go to the settings tab on the right and set use same settings as incoming mail .
