Greetings, I am having a problem with xp_sendmail on a SQL Server 2k only. This works in 7 but not 2K. exec master.dbo.xp_sendmail @recipients = 'email@example.com',@message = 'I have completed' I get: Server: Msg 18031, Level 16, State 1, Line 0 xp_sendmail: Could not resolve recipient My mail runs fine for the jobs I use with the SQL Agent. It's only when I try it from ISQLW. I've tried my exchange name "jfogel", "firstname.lastname@example.org" and my yahoo account. I upgraded to sp3 in hopes that the problem was there. Any thoughts?
