deleting mailbox hasnt deleted disc space - Exchange 2010

I have deleted several old mailboxes off exchange 2010, but it hasnt free'd up any disc space. My policy is set to retain deleted mailboxes for 14 days, but how can you force the deletion? I need this additional Disc space asap.

I am sorry for the previous post...

When you delete the mailboxes,it wont release the space immediately.
If you want to create the space then you have to perform an offline defragmentation on the database.

Hello,

You won't reclaim disk space by deleting mailboxes. When you delete mailboxes you free up space inside the database but the database will never shrink unless you do an offline defrag, which is generally unnecessary and would require 1.5 times free disk space as the size of the database.

When you delete some mails or mailboxes from exchange database,it doesn't release the space to the disk.Instead it creates some white space and you can gain the white/free space only after doing an offline defragmentation.
But before that,delete your unwanted mailboxes and put the retention of deleted mails and mailboxes to 0 days.Then perform an online maintanance and check for the event-1221. which gives the white space available on the database.
Based on the white space available on the database,you can plan about the offline defragmentation.
As per Microssoft recomendation,you  need to have a minimum of 20% white space of the total database size to perform an useful offline defragmentation.

You would need to reduce your deleted mailbox retention time.

If you need the additional disc space immediately then delete any unwanted data from that particular drive or if logs file or present on the same drive,then you can either move the logs to other drive or take a full exchange backp which will purge the commited log files.
