Have you compacted and still see the prompt? And are you running XP with
Service Pack 3 installed? If yes to both, the following may apply.

There is a growing number of programs that may be causing this after
installing SP3. Do you have any of the following?

IBM Rapid Access keyboard.
Windows Desktop Search
Window Live Mail
Mailwasher.
Nero.

Various anti-virus, anti-spyware and third party firewalls, especially if
they were running when you installed SP3.

You could also download RegMon:

Run the program and monitor the Compact Count Check registry value by
filtering on: Compact Count Check.

This should identify the program that is causing the rapid increase in the
Compact Check Count registry value.

For some reason, the "To free up disk space, Outlook Express can compact
messages" reminder is popping up on my computer within two days of my last
compacting. Plus, it doesn't wait until I'm closing out of Outlook. It
just
pops up and, if I cancel it, pops up again in about three minutes or less.

The only change I've made to my system recently is installing as new, much
larger hard drive.

I can see the value of compacting messages, but this is becoming
bothersome.
What can I do?
