Softhing (http://www.softhing.com) has updated Entourage Exchange
Accounts Optimizer to version 1.5.0. With Entourage Exchange Accounts
Optimizer, you can ensure your on-line Exchange mailbox never gets
full. The upgrade has a redesigned interface.

It also shows detailed info during the progress of operations. There
also are various internal improvements, and the range of days has
been extended to 1,200.

This utility automatically moves old mail from your Exchange account
to a replicated structure within Entourage. You select how many days
of mail to keep in Exchange and EEAO does the rest. It ccan handle
multiple accounts and be set to run automatically. It works in both
Mac OS X 10.4 (“Tiger”) and Mac OS X 10.5 (“Leopard”) Entourage 2004
and 2008.

Entourage Exchange Accounts Optimizer costs US$30 for a single-user
license. However, version 1.5.0 is a free update for registered users.
