We're finding that the differential incremental backups we run against
our Exchange Information store are the same size as fulls of the same
data. Has anyone else seen this? Is this normal?

It's normal if you have a large traffic profile and a lot of deleting
is going on. Apart from that no, you should check what's going on.
How many log files are you generating per day?
And does your backup solution record the actual number of megabytes
backed up or does it tell you porky pies?
