In Outlook XP, go to the tools menu and select e-mail accounts. Make sure the radio button next to "View or change existing e-mail accounts" is checked and click next. Highlight the proper account and click Change. Click the "More Settings" button.. Click on the Outgoing Server tab, check the box next to "My outgoing server (SMTP) requires authentication" and enter a username and password. That should do it.

Please contact your system administrator. <server.domain.com #5.5.0 smtp;553 Authentication is required to send mail as <[EMAIL PROTECTED]>> I continue to recieve this message when i try to send an email to a peticular domain. The strange thing is that it works on at least one user here, but there are several others that cant send mail there. We are running W2K and E2K both with latest service packs. All the users are using Outlook XP. Thanks in advance. The recipient is able to recieve mail from others. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
