Here's a heads up on a new product coming out that looks interesting. It's
called MailShadow and is made by Cemaphore (www.cemaphore.com). The product is
geared towards DR scenarios and works at the transaction level so there are no
issues with database level corruption (like you see with other Exchange replication
I haven't seen the product yet in action so I'll reserve my judgement for then
but if it works like they say it could be a great addition for companies looking
to replicate Exchange data to other locations.
