Exchange 2010 database / white space

I am not sure I understand exactly how this works and wanted to look into this before space becomes a major issue.
The exchange server is running on a virtual machine and has a limit of 256 GB on the drive that contains the database. Currently the drive is at aprox 215 GB.
I had a few users who had huge mail boxes delete old items.  
I ran the cmdlet to get the database size after the items were deleted and it is still too large aprox 205 GB.
I then ran the cmdlet to see the size of the white space / available new mailbox space and it is aprox 40 GB.

My question is will exchange use this 40 GB of white space going forward?  Or will I have to figure out a way to defrag the database, wich will be a challange becuase of the limited storage space or have to move the mail boxes to a different database some where else to gain the 40 GB back.

Thanks

Generally, the Exchange 2010 Database is Defragmented automatically in the Nightly maintenance that runs at the time you configure. Also, Exchange uses white space in the Database as efficiently as possible. This means that the databases will generally grow, but don't often shrink very much because the space used is reused when it's freed up. If you want to, it is possible to create a new mailbox database and move the mailboxes to it without incurring any real downtime.
