Emails Sent by Users are Stuck in Outbox/Draft Folder
ENVIRONMENT:
- Exchange 2007 with clustered mailbox Server running on Windows 2003 64bit
- 2 HUB & 2 CAS Servers
- SMPT gateway (Ironmail from McAfee)
SYMPTOM:
Emails sent by users were stuck in Outbox/Drafts folder. We had infact asked some of the users to send 5-10 test emails for a couple of days to study the case. Some emails were also sent using iPhones and blackberry handheld. So the ground fact was that, not all emails were received by the recipients. 2-3 emails were stuck in the Outlook’s Outbox or Draft folder. This was the case when emails were sent using OWA (outlook web access) as well.
CASE IDENTIFICATION DATA:
We escalated this issue with Microsoft and thru’ analysis of server logs confirmed that “MSExchange Store Driver - 1014” warnings were logged for the users who had faced the issue with emails stuck in the Outbox.
Issues encountered during the test case:
Restarted the Microsoft Exchange Transport service on both HUB servers. Moved the 3 affected Users’ mailboxes to another mailbox database.
During the mailbox move, the operation was canceled manually, and when the problematic users tried to access their mailbox, they received an error stating that there’s currently a move operation running.
We got this sorted by running Clean-MailboxDatabase for the source and the destination mailbox databases. And moved the CCR CMS to the passive node.
All users including the affected users could access their mailbox normally.
ACTION PLAN:
move one of the affected mailbox to another database
The above plan didn't sort the issue though.
By investigating the logs further we could find something fishy in Monitoring tool “Quest software” which was installed in your Exchange infrastructure. We also noticed that this monitoring tool can cause the generation of similar symptom that we are facing currently. So in order to isolate the issue, we temporarily disable all the Quest related services in the two Hub Servers and two Mailbox Servers for three days and kept the antennas monitored for “MSExchange Store Driver - 1014” alert was generated repeatedly.
CAUSE:
A third party “Quest service” was installed in Exchange server which caused failure in MSExchange StoreDriver to open the message item and hence resulted in failure for submission.
RESOLUTION:
We had disabled the “Quest services” in Exchange servers and further to this no alerts were logged related to MSExchange Store Driver. Also during this period, users did not face the issue of emails stuck in Outbox/Drafts. We concluded that Quest services are incorrectly handling some emails which make the Emails stuck in Outbox.

Real-Time Intranet (SharePoint) Replication: Production Site to Disaster Revovery Site
SharePoint 2010 real-time replication to the Disaster recovery site using third-party tool; DocAve from AvePoint is one among them
We have been using this software for SharePoint replication since last 4+ years. It's a wonderful software designed for MOSS 2007 & SharePoint 2010 environment. Lot of features are embedded to it. We just got replication module licensed as replication from production site to DR Site was our concern. All we have to do is to first restore the destination site using the latest SQL DB site level backups. We used an independent server for the DocAve Enterprise manager. DocAve 6 Client Plug-ins were installed on the below Web Front-End servers of both source and destination site. That's it. The configuration is pretty simple. It does real-time replication instantly in less than a minute.
We had slight issues when we activated real-time replication. However, the issue got stabilized after re-scheduling the replication method to trigger incremental replication after business hours. Accessing database from different process like backup plan and real-time replication plan could have been a conflict.

Scheduled Maintenance Plan for SQL Express DBs
Automate Database backup with SQL Express using scripts and batch schedule
Let us automate database backup in SQL Express with mixed Windows and SQL Authentication running on Windows 2008 Server. This material was tested with Microsoft SQL Server 2008 R2 Express and SQL server 2005 Express Edn.
SQL Server 2008 Enterprise comes with Maintenance Plan feature. SQL Express edition lacks this feature. But you still need a backup.
Backup automation with SQL Express can be carried out by following the steps:
i) Create the script in sql to backup all your databases.
ii) Execute the script by initiating it from a command prompt (SQLCMD command).
iii) Schedule the script using Windows Task Scheduler.
i)
-- script starts here
DECLARE @dbName VARCHAR(33) -- database name
DECLARE @path VARCHAR(99) -- backup path
DECLARE @fileName VARCHAR(99) -- backup file name
DECLARE @fileQuarter CHAR(1) -- variable portion of file name
SET @path = '\\192.168.16.193\backup\TestDB\Bkp\'
-- the above path is a remote location. make sure path is changed according to the environment you may have.
-- Returns a Numeral from 1 to 4
-- Each Quarter you get a new backup file name
SELECT @fileQuarter = CONVERT (char(1),(MONTH(GETDATE())+2)/3, 112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
-- Exclude all System Databases, if Needed - 'master','model','msdb'
WHERE name NOT IN ('tempdb')
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @dbName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @dbName + '_' + @fileQuarter + '.BAK'
-- Use INIT and SKIP to overwrite previous sets
BACKUP DATABASE @dbName TO DISK = @fileName WITH INIT, SKIP
FETCH NEXT FROM db_cursor INTO @dbName
END
CLOSE db_cursor
DEALLOCATE db_cursor
-- script ends here
--save the above script in .sql format (Ex. Bkp.sql)
ii) Create a windows batch file with .bat extension (Ex. bkp.bat) the content of which is as follows:
SQLCMD -E –S TST-APP1\myDB -i "c:\yourlocalfolder\Bkp.sql" -o "c:\yourlocalfolder\Log.txt"
iii) Now create a scheduled task from windows control panel. Make a schedule to run the batch file 'bkp.bat' file on a daily or weekly basis.
It is wise to take the same backup to a tape drive as per the backup plan: daily, weekly and monthly so that you don't leave a question or thought.
Serious security threat at International Airports
''this is true. I travel 2-3 times
in a year to Calicut (my hometown); and 'am a periodic traveler to other countries. I have noticed the vulnerable gaps and the lapse in many
airport procedures'; which the authorities are not even concerned about. Their basic role is to mint money..! Their basic oath to the nation is to: 'live to trouble others' and not 'live to make pride'..! We have to
understand the ground facts and needs to look at the big picture; the image of
Calicut city as an instance and India as a whole is represented at the entry ports and those
who have closer ties with the authorities and with political influences are even
exempted. Shame on the fragile policies..!
Another key note which I would like
to put up here is; (which evidently most of you might have noticed) Most of the
Customs authorities sit at the check points after consumption of
liquors. If the responsible authorities check the airport staff with
'Breathalyzers Screening Devices' to check a person's blood-alcohol content,
then we are sure it will be a flash news.
In reality, we need to have an action oriented Govt.; who listens to the public. A cell with falcon eye, who monitors the evil factors.
