I am assuming you're archiving (saving) the messages in another local OE
folder.

Why it happens:

Avoid Such Corruption in Futu

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

- Empty Deleted Items folder daily.

- Disable Background Compacting [N/A in SP2] and frequently perform a manual
compact of all OE folders while "working offline". More at
http://insideoe.tomsterdam.com/files/maintain.htm.

- WinXP SP2 only: Do not shut down your machine while Windows is
automatically compacting your message store.

- WinXP SP2 only: If your machine is fully up-to-date at Windows Update,
installing the following patch (KB918766) will help to avoid such data loss
in the futu

This patch will be included in the next Cumulative Update for Outlook
Express/WinXP SP2.

- Your anti-virus application's email scanning feature can also cause such
corruption. Disable it. It provides no additional protection.

For saving emails, I have a number of different files set up, and move
emails that I want to save into them (as most people do, I imagine)
However, I notice that when a certain number get put into a saved file (or
a
certain total size) the emails you attempt to put in just disappear!
1. Is there a way to know what this size is?
2. When you are approaching that level?
3. Where the ones have gone that appear to have disappeared?

Thanks in advance for any help.
