Mailbox Database.edb size

    Question

  • hi,

    we have exchange 2007 sp2. 

    Get-MailboxStatistics in the exchange management shell shows 26 mailboxes with a combined size of 35497 mb. event 1221 shows free space of 15972mb, giving a total of 51469 mb equating to 50.3 GB.

    from within windows explorer, the properties of the  mailbox database.edb shows a size of 53.1GB.

    can anyone account for the difference between the 2 GB figures?

  • it can be dumpster size or the open references of the mails which recently moved/deleted.

    Dumpster- will clear as per the retention period defined

    Open references- will turn into white spaces as the online maintenance progresses.

  • Hello

    There are few things that you would not counting here.

    1.Deleted emails which are in dumpster also counts in size till they expired in retention.

    2.Disabled mailboxes also include in it till their retentions expired.

  • get-mailboxstatistics shows the amount of data present in the mailboxes. Exchange database size wont be reduced. 1221 information says that the amount of white space that can be reclaimed as free space after offline defrag is 15972m. In case if your aim is to reduce the size of the EDB File then rather than affording downtime to perform eseutil /d you can consider moving mailboxes to a different store.

    Let me know in case if you have any additional queries and please brief about what you are looking for.

  • I am not concerned about reducing the edb. My query relates to why there is a 2.8gb difference in the 2 figures.
