I followed the instructions that were posted in your link.
It said the changes were successful.
When I check it normally and click ok to get out it says the numbers arent right but it does keep them to what I changed it to.
Is this normal?

You can create the system policy according to the requirement and add the required DB in the policy. This will apply the policy to all user which are part of that DB.
I believe the normal check will not display the changes (since its a "hack" in a sense). To verify you might want to setup a test mailbox w/ an increased limit and then just send a bunch of large files to it to verify just to be safe. Not the most fun thing to do, but then you won't go to sleep wondering if it really works.
