Size of .edb differs of size displayed from Exchange 2010

First excuse-me from my english.
My problem :
I do not understand the difference between the disk space used by the EDB file and the size displayed by exchange.
The size of my EDB is 49GB without logs.
I use one mail db per user.
The size from exchange shell: 24.51 GB (26,314,299,925 bytes)

My version of exchange is 2010 SP3

Can you help me to reduce the file size?
Thank you

See my comments in your related question.

It looks like that will answer this question as well.

Make sure to make a backup of any database before running this utility.

Hi Jose.

Exchange DB file always increase the size of its edb file whenever new user is added and they have mail transactions. But in case you delete big users still DB size is not reduced so it does not mean that DB is full.

As per EDB architecture, Exchange itself do online defragmentation of EDB files which clean up disconnected mailbox after defined retention and also clean up deleted items from user's dumpsters.

Even after cleanup of above, EDB file won't reduce as it will contains white space, which is sought free space and will be used by new accommodated users or existing users with their future mail transaction.

In short if you don't have any space crunch with disk space so nothing to do with it and let it be like that.

In case if you want to check white space of your EDB file please check with below powershell:

get-mailboxdatabase <DBName> -status | ft Name, *Available*
