I have the email profile set up and I can start/stop/test the SQLMail
service w/o problem. I can send email thru xp_sendmail. I only found this
error by chance, when I glanced at the SQL Server Agent Log.
[260] Unable to start mail session (reason: Unable to logon (reason:
MapiLogonEx Failed due to MAPI error 87: Invalid parameter); check the mail
profile and/or the SQLServerAgent service startup account)
