Hi - I can't get db mail working or delete the db mail queues. I've restarted sql server and sql server agent service. db mail stored procedures is enabled in surface area configuration. service broker in msdb is enabled. i've tried to delete the mail queue by running the following: DECLARE @GETDATE datetime SET @GETDATE =GETDATE () EXECUTE msdb.dbo.sysmail_delete_mailitems_sp @sent_before = @GETDATE ; GO But when I run the following there are still a number of mails listed with STATE as 'NOTIFIED'. EXEC msdb.dbo.sysmail_help_queue_sp @queue_type ='mail' These can't be removed. Any idea on how to get rid of these and clear the database mail queue. The enviornment is SQL Server 2005 SP3 on Windows 2003 SP2. I think if I delete the queues then the emails may be able to be sent. I've also tried to stop and restart the db mail by running the following two lines but get this error: The activated proc [dbo].[sp_sysmail_activate] running onqueue msdb.dbo.ExternalMailQueue output the following: 'Error executing extended stored procedure: Invalid Parameter' Code run to stop/start db mails is: sysmail_stop_sp --stopping the queue using sysmail_start_sp -- starting the queue using Any idea on how to resolve this?
