I have a few users logging into MS Outlook 2000 and they send email and it immediately gets bounced back with a No Transport Provider available. I went through the configuration in Outlook and the entire POP3 Account is set up correctly. I updated and put on the MS Windows Patches and such. I can send email from the providers Web-Based facility so I know the account works. I tried changing the SMTP Server and I also tried uninstalling and reinstall MS Office. And still no luck. Anybody have any suggestions. Thanks
