Up to last night, E-Mails that I sent from Microsoft Outlook and Outlook Express were delivered.

As of this morning, none of the many E-Mails I sent were delivered- yet they show up in my ‘Sent” folder.
Anyone ever experienced this?

...but I received E-Mails

I have experienced something very similar. My home internet server is cox. When I try to send out email messages from other providers, it will not go through. Spoke to Cox and it has to do with them. I am not very technical, but they are my server for emails, and because of security concerns, they will not allow my emails to come from another server.

To check this, open Outlook, go to Tools, go to Email accounts, click on View or Change Exisiting email accounts, click on Change. This screen will now give you the Server Information (see right hand side). Make sure the information is correct. Don't worry about changing anything, all you have to do hit "cancel" on any screen.

If you have more problems, try calling your Provider.

Thanks very much Leevena.

This helped. The POP#3 was incorrect. Somehow- must be one of us of course-changed it so there was no periods between the pop.1and1.com.

Thanks again
