    Yes that includes deleted mailboxes.  If you delete mail or mailboxes the database size will not decrease but you will create "white space" for new data to be written to.  The database file will increase in size when there is no more white space to hold new data.  You can reclaim the white space by running an offline defragmentation of the database but this is not recommended is normal situations.

    The daily maintenance (online defrag) generates event ID 1221 which will tell you how much white space is available in each database.

    Cheers, Steve

  • The white space is inside the database so if you have a 64GB database and you delete 4GB of email, once that email is out of the retention period you will have 4GB of white space available.  Your total database size on disk will still be 64GB though.  If you write 6GB of data to the database now the 4GB of space will be used up and the total database size on disk will be 66GB.

  • you are telling that when i delete any mailbox, the "white space" will increase automatically????

    And if i create any new mailbox, it is using the space of 'white space"  ????

    If the white space is finished, it will take the space from physical database???
