Sell the concept to the users.  Our users would never accept it -
they've got to see that stub.

Subject: FW: Microsoft Recommends Against Stubbing



I'm looking to Purchase Sunbelt SEA but maybe I should not!

This is from the competition that's try to sell me an appliance.

Stefan, I had the opportunity to view the Sunbelt demo today. I did not
know that they used "stubbing" instead of journaling. 

Here's some information to consider straight from Microsoft: 

>From Ferris Research:

An important feature of email archiving is called "stubbing." This is a
process whereby an entire email or just the attachment is removed from
Exchange and replaced with a "stub" file. When the user opens the
message in Outlook, the stub file retrieves the archived email and/or
attachment from the archive. The benefit is reduced Exchange storage.

Microsoft is now recommending against the use of stubbing:

*       Search problems. If you retain months (and years) of stub files,
several hundred thousand messages will be processed in this way. The
probability of successfully locating a specific message with Outlook
search is greatly reduced when you do not have a significant portion of
the message body available. Users need to go to the archive multiple
times to find a desired message. Third-party email archiving solutions
solve the problem of mailbox size, but they reduce search efficiency and
increase user time performing multiple searches. 
*       Performance. If folders contain a large number of messages, even
ones just consisting of stubs, Outlook slows down a lot. 

Microsoft therefore recommends that third-party email archiving
solutions be configured to move email content completely out of the
mailbox without retaining stub files in the mailbox. For more
information, read this TechNet article
<http://technet.microsoft.com/en-us/library/cc671168(EXCHG.80).aspx> .
The information targets Exchange 2007, but it is also relevant for
Exchange 2003 systems considering third-party email archiving.
