The procedure then calls sp_send_dbmail to send the emails.I get an error on the job regarding a connection timeout. I'm not sure if the timeout is returning from the exchange server or the SQL server.Any ideas?Exception Type: Microsoft.SqlServer.Management.SqlIMail.Server.Common.BaseExceptionMessage: There was an error on the connection.
