Exchange 2010 defraf database not releasing space

I have Exchange 2010 with the default database. It got to over 180 gig. I created another database and moved a lot of user. I successfully  ran a defrag on the first database however it is still 180 gig. When I check white space it shows a total of 812 meg. Currently there are only 10 mailboxes on there and they are small.

How can I shrink that database?

Just move all user to new DB. Delete and create fresh one.

I thought about doing that. I just worry that it could break something and if I delete it, I can't get it back. Is there any possible issues I could come across by deleting that one?

Once all mailboxes are moved to new DB. Then you won't face any issue.  In case this is first DB. Then you might need to follow my article.

If you have Public Folder, make sure you new DB is also pointing to PF DB. Rest I don't see any other risk.

Thanks for that link. I have never deleted the first mailbox because I was afraid of possible issues. I would still prefer to keep this one instead of going through all those steps if possible. Any idea why a defrag would not shrink the database>

FYI Defrag db also create new DB. So you already created a new DB, that old DB is already gone. With my article, you can delete this DB without any issue. Still you feel risky. You can leave this and create new DB's. However, I don't see any risk in deleting and recreating it again.

The first database does have some system mailboxes in it - but those can be easily moved and Exchange will not let you drop the database if it is being used.

Offline defrag is a waste of time with Exchange 2010 - you should have just deleted the database instead.

I get that defrag creates a new one but it is supposed to overlay the old one. If it did not overlay it, where would it be? I assume I could manually do that?

An offline defrag will create a new database using the old content.
The old mailboxes are probably still retained due to deleted mailbox retention within the database - although I am not sure if that does survive an offline defrag because I haven't done one since Exchange 2007 was released. Complete waste of time in my opinion.

I would just forget about why it is happening, drop the old database and create a new one.

When I saw "mailbox "retention"  I realized that was probably the issue. I changed the retention settings to 0, re-ran defrag and shrunk the database completely. Next I will back that up and go through the process of removing the first mailbox store
