Data loss using OE6 compaction function

The following may be of interest to those using Outlook Express

· I use Outlook Express as a mail client.

· I noticed 2 years of sent emails missing.

· I checked the file sizes and these suggest some emails were not
indexed

· I compacted the sent directory

· The emails were not restored to the index and appear to have been
deleted

· Using alternative software I located the lost emails and some it
would appear I sent in 1799!!!!

I believe there is a risk of loss of emails using the compact folders option
in Outlook Express

You /must/ compact periodically, but if you treat OE with some TLC (and
backup your message) you will lessen the chance of this happening again.

Why does OE insist on compacting folders when I close it?:

Compacting your folders periodically is a must to keep OE functioning well
and at some point, you may lose all your saved messages if you don't. When
you delete, or move messages, the space they had used remains until you
compact.

***Never touch anything until the compacting is finished.***

See:
www.oehelp.com/OETips.aspx#2

With SP2, automatic background compacting was removed due to problems it
caused. Now you will get a prompt to compact after 100 OE closings, which
you should do, and don't touch anything until it has finished. If you
compact manually, at your convenience, this will also set the counter back
to zero. See this for more information:
http://www.insideoe.com/files/maintain.htm#compact

If you are fully patched, you will also now see a copy of your dbx files
being copied to the Recycle Bin as BAK files. Should something go awry when
compacting, the messages can easily be restored from this backup. A manual
compact will also reset the counter in the registry back to zero now.

For more info, see the information outlined in red here:
www.oehelp.com/OETips.aspx#2

General precautions for Outlook Express:

Do not archive mail in the Inbox or Sent Items. Create your own user defined
folders and move the messages you wish to save to them. Empty Deleted Items
folder daily. Although dbx files have a theoretical capacity of 2GB, I
recommend about a 300MB max for less chance of corruption.

Information about the maximum file size of the .dbx files that are used by
Outlook Express:
http://support.microsoft.com/kb/903095

After you are done, follow up by compacting your folders manually while
working *offline* and do it often.

Click on Outlook Express at the top of the folder tree so no folders are
open. Then: File | Work Offline (or double click Working Online in the
Status Bar). File | Folder | Compact all folders. Don't touch anything until
the compacting is completed.

Turn off e-mail scanning in your anti-virus program. It is a redundant layer
of protection that eats up CPUs and causes a multitude of problems such as
time-outs and account setting changes. Your up-to-date A/V program will
continue to protect you sufficiently. For more, see:
http://www.oehelp.com/OETips.aspx#3

In Tools | Options | Maintenance: Uncheck Compact messages in background and
leave it unchecked. {N/A if running XP/SP2}.

And backup often.

Recovering the missing data: http://www.oehelp.com/OETips.aspx (#2 and #4)
and http://support.microsoft.com/kb/918069 (see Notes section under
Resolution section; Please note that you do NOT need to install KB923694 or
KB918766 if your computer is fully-patched at Windows Update!)

Avoiding Such Corruption in Future:

- Don't use Inbox or Sent Items to archive messages. Move them to local
folders created for this purpose.

- Empty Deleted Items folder daily.

- Frequently perform a manual compact of all OE folders while "working
offline". More at http://www.insideoe.com/files/maintain.htm

- Do not cancel Automatic Compacting, should it occur, and do not attempt to
close OE via Task Manager or shutdown your machine if Automatic Compacting
is taking place.

- Disable email scanning by your anti-virus application. It can cause
corruption (i.e., loss of messages) and provides no additional protection:
