  I'm running an Exchange Server 2010 on Windows Server 2008R, everything goes well except the .edb database file didn't get bigger since 14 May. I'm very worry about this and wander why the datas didn't write to the database.
  Please help. thanks a lot

Hi it may be that there is lots of white space in the EDB files.  If some space reclamation task has been carried out such as deleting mailboxes and such the EDB files doesn't shrink it just becomes white space
Do a get-mailboxdatabase | get-mailboxstatics from the exchange PowerShell and that will list details of the mailboxes on your database should give you some useful info. Failing that do a message tracking log query from the emc toolbox that will show all the emails I think  EDB between given dates

Thanks cwstad2.
  I performed Get-MailboxDatabase | Get-MailboxStatistics >> c:\Get-MailboxStatics and it shows there are only 436 users and most of the StorageLimitStatus is BelowLimit,fews are IssueWarning.
  I just have no idea why the database file was modified at 2015/05/14 3:21 and atfert that it didn't increase any more

Someone isn't patching their server.
The information about the database isn't updated until the information store service is restarted.
Therefore as the date is in May, you haven't been installing updates, which require a server reboot (and therefore the service to be restarted).

This command will show you how much white space is in the databases on the server:
Get-MailboxDatabase -Status | Select Servername, Name, AvailableNewMailboxSpace

Thanks Simon.
  This must be the reason:
   1.773 GB (1,903,394,816 bytes)

But the disk which stores the database has more than 1.7TB space avaliable, what should I do to make database file work porperly?
Simon Butler (Sembee)ConsultantCommented:
You have 1.7gb of space available. Exchange will use that space first. There is nothing wrong that I can see.

If you have users who are regularly getting lots of email and then deleting it, then the database size will not change much because the white space is being used.

Re-run that command regularly to try and get an idea on how the space changes.

Thanks Simon.
  I rebooted the server just now since it's moonnight and checked the .edb file and found nothing changed,same modified time,same size. Maybe the white space is enough.
  I'll keep an eye on it, if there’s any question, I hope that I can turn to you.
