AvailableNewMailboxSpace Accuracy

How accurate is AvailableNewMailboxSpace value of a mailbox database. I have new databases that moved new mailboxes to, eventho the disk has a lot of free space the AvailableNewMailboxSpace value shows 50 KB which i have no idea why?
this is a new database so there should not be any soft deleted mailboxes or white spaces in there

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

HI Riaz,

You need  to use ESEUTIL /MS to get an accurate information of white space.

https://blogs.technet.microsoft.com/rmilne/2013/08/20/how-to-check-database-white-space-in-exchange/

AvailableNewMailboxSpace show how much space is available in the root tree of the database. It does not apply in the free pages within mailbox tables, index tables, etc.  It is not totally representative of the white space within the database.

Regards
Valentina
