I am using Outlook 2002 in XP Home and sending a message from a 1and1 web based email account to a hotmail account. I have logged into the 1and1 account in Outlook using both POP3 and IMAP connections. When I try to send a message to the hotmail account I get the message "the following recipient could not be reached ... 550 must be authenticated".

Check the account settings from your ISP to make sure they are correct. It may just be the user account configuration is not correct. If I recall correctly it is under Tools - Email Accounts.

Hal. Thank you. I just needed to tick that my outgoing mail server required authentication. Easy when you know how!
