Quest have again created an interesting product: Availability Manager for Exchange.
It works by having an agent (or MOM) check the status of the server or store. When the server or store is down, mailboxes (empty ones) will be created on another server and mailbox information on the user's account will be updated to point to the new location. A user needs to stop and start Outlook to access the new mailbox. When service is restored, users can connect back to their original mailbox. The data from the temporary mailbox is copied to the original one.
Interesting, especially for users who always need to be able to send and receive mail (dispatchers etc...). It is all a bit more automatic than Microsoft's Dial tone recovery procedure which, essentially, provides the same basic feature.
