THANKS A MILLION... For 2 full weeks I thought I would go crazy.. I tried a fix suggested in another link, which suggested something to do with the DNS, but that didn't work.
Every other fix proposed was complicated, so luckily after 6 hours of research tonight, simply removing the profile created initially and then following something proposed by ramona, all my mail came thru. At the point where I was registering my screename, I cancelled when it was connecting. This is after inputing date of birth etc. then clicked next, then next, then finish. AND KABOOM... All mail went through.
Hurrah guys.
Again, after redoing the profile setup follow this:
I don't know about that error but,
Here is the workaround I used for the "Mailbox Creation Failed" error when setting up an existing webmail account in Netscape 7.x mail, FWIW
From a MAIL window, go to Edit > Mail&newsgroup Account Settings.
Click on Add Account > Netscape Webmail account > "I have an existing account".
Enter the screenname and password for the existing netscape.net account under "Current Member sign-in". The Netscape Mail Setup window should appear, asking for the name you want to appear in the "from" field.
After typing in your name, click the Next button, and wait a few seconds after the "connecting to server" message appears, then click "Cancel". Then click "Next", then "Finish" and the Netscape Webmail account will be set up in Netscape 7.x Mail.
