Hi Steve,

This is not Data Protection for Exchange stopping you from doing it,
it is the Exchange Server backup API that is stopping you.
It looks like you were actually able to submit the incremental backup
request to the Exchange Server... but then the Exchange Server
failed the backup attempt with the message below.
That means that even the Exchange Server is confused.
I would stop and restart the Exchange Services as a first attempt.
If that doesn't work, try rebooting.

Thanks,

Del
