I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing.

Are there messages still in Deleted Items?  Deleted Items will count against the total size, but items in the Deleted Items retention period won't.
did you empty the deleted items as well?

nothing in deleted items. I think it's an issue with exchange retention
as we use a NAS snapmanager and not tape backup i don't think it's showing as backed up, thus not clearing down
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

1. Your nightly online maintenance needs to run and you will see a 1221 in the event log designating the amount of space that can be recovered more here

2. However, that said you are correct about the backup issue i.e. within Exchange 2007 there is a setting

* Mailbox properties--mailbox settings- storage quotas

* Under deleted item retention there is a setting that says "Do not permanently delete items until you backup the database"   De-select that, save the settings and then wait for you nightly maintenance to run.  You will see the 1221 when done or if you don't want t wait you can force it to run all the time TEMPORARILY and then when you get a 1221 you will be good to go and then you can turn your nightly maintenance back to the normal 1-5AM time slot or whatever works best for your firm
