You won't see a reduction in the pysical size of the database without doing an offline defrag, and I wouldn't do that unless you are running very low on general capacity, its not without risks, can cause data loss etc. The 'online' maintenance task will show how much 'free space' is available in the current database, and this is what will increase if you get your users to delete data (after the retention period has expired for the data items of course). This 'free space' is also known as white space, and should be overwritten before the physical size of the database increases.

The first message is reporting that your database can grow to 25GB (so the registry key has worked).
The second message is just reporting how much space in the database is currently free, before Exchange will have to start increasing the size of the database. It's nothing to worry about.
Your databases will grow to 25GB quite happily.
