Failure to execute msdb.dbo.sp_send_dbmail

Question

I am getting this error:

Msg 229, Level 14, State 5, Procedure sp_send_dbmail, Line 1
The EXECUTE permission was denied on the object \'sp_send_dbma

Answer 1

I accidentally changed the "Run As" option for the SQL Agent Job - Step from "[User]" to "(Not Specified)". That caused my Job to start working.
