This could be a server error or down for maintenance. you may well find it will rectify it's self after a few hours.

No attachment, just a link in the 'contact us' part of the web page that brings up my email box, i write, click send & then the green 'sending in progress' progression bar arrives & 3 quarters of the way through, it quits & i get the above message in the sending box!

Marg7, do you mean i need to ask my isp if i can send mail to that address! The address is a medical organisation so i'm sure it's valid & ok!

As i say, other mails i send seem to work ok, maybe it is a temp error!!

What happens if the firewall is disabled briefly ?

You can try to change the server from to


Some time ago a lot of people where advised to change to orangehome from Freeserve and,ive been with Freeserve/Wanadoo/Orange for some years now and still use the Freeserve smtp with no problems.

You say it is a "contact us" link on a web-page. Does clicking on the link actually open OE for you to write the message, or is it a message box within the web-page?

Hi all
Yes skidzy, i been with wannadoo too & freeserve. Erm, not disabled firewall as all was ok with other mails i sent before!!. Could it be a firewall prob if i can send mails to myself & links to other pages!!E.g, if i right click this page & send link, all is ok! I use Firefox

Do you mean when i right click on the firewall's icon in taskbar & Exit? Maybe i'd need Windows firewall to replace for a time? But is this necessary if i can send myself a mail??

It was a 'contact us' link that brought the OE open to write the message. It was a [email protected], .com & was only a fiew words of a query i wrote!!

Hi, this 'my server requires authentication' box is unchecked.

I seem to be able to send mail via Outlook Express 6 to myself & others, is it that the mail i was sending that gave the error was the problem.
How come i can send mail ok to most place, but not this one!!

Some page links i send, this happens a lot!!

Try logging into click here
and if the email is still on the server,try sending to yourself from there.
If this works,we know its an OE setting somewhere.

This type of error is sometimes caused by corruption to your Outbox. No harm will be caused if it doesn't cure the problem

Using Explorer navigate to your store folder which, if you haven't moved it, is located at C:\Documents and Settings\{user name}\Local Settings\Application Data\Identities\{long name}\Microsoft\Outlook Express and delete Outbox.dbx.

You may have to show 'hidden' files in Folder Options to see it. Open Outlook Express and a new, empty Outbox will be created by Windows.

Skidzy, i can send a mail from my webmail address to my Outlook Express address )same address.

My Outbox is empty Burr Walnut.
When i get to c:/documents & settings, i then get administrator & all users, not what you wrote.
I click on administrator & then get some folders with strange number & letters for names. Can't fing application data or identities anywhere!!

It seems my OE won't send to that address, webmail does!! But seems just certain addresses!

As I said above you may have to show hidden files and folders, via Control Panel > Folder Options.
