To remove the message at Windows Startup that says:
"To free up disk space, Outlook Express can compact messages. This may take up to a few minutes."
If you using Windows XP, there is a registry value called:
"Compact Check Count"
It is located in the Registry in a key resembling this:
HKCU\Identities\{51909A0B-63EE-4EB3-A9A2-7CFA23C1ADCF}\Software\Microsoft\Outlook
Express\5.0
Set the "Compact Check Count" value to 0.
Every time you exit OE (not when you open it), the value of the counter increases by one
increment (increment is not a verb so you can't increment something and a
counter cannot be incremented). When the value of the counter gets to 101, the
next time you close OE you will be prompted to compress the messages.
