General OE User Caveats:

- 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:

Disabling Email Scanning does not leave you unprotected against viruses that
are distributed as email attachments. Norton AntiVirus Auto-Protect scans
incoming files as they are saved to your hard drive, including email and
email attachments. Email Scanning is just another layer on top of this. To
make sure that Auto-Protect is providing the maximum protection, keep
Auto-Protect enabled and run LiveUpdate regularly to ensure that you have
the most recent virus definitions.
