(X is configurable.) The message invites the user to exit Outlook and gives a URL to manually start a backup." So, no, it doesn't look like that's possible. There *is* a link on that page to an MSDN post which describes a script which can use VSS to copy individual files to a new location. However, there's no integration with backuppc, and there's no identification of open files, so you need to know in advance which files might need to be copied with VSS. Don't do that to yourself. Just use a backup program that supports VSS.
