Problems sending with Entourage

[A1Exchangers]

I just bought this Mac and loaded Office 2004. I have had problems sending emails to specific email accounts such as hotmail accounts.

I receive the following notes:

relaying mail to hotmail.com is not allowed
Error: -17099

Thanks in advance.

Sounds like your ISP is blocking emails to Hotmail.

Error -17099
Relaying to <the email address> prohibited by administrator
Email could not be sent
Account name (my account name)
Error -17099

Error -17099 is an Entourage error kSMTPServerReplyErr, and is returned when the SMTP server has returned a permanent or transient error or returns an unexpected result code.
