3 methods to convert EDB to PST

Exchange 2007 and versions earlier to that had user mailboxes saved in storage groups. It became possible to take backup of these user mailboxes by simply backing up those storage groups. However, in the newer and more recent versions of Exchange server user mailboxes are now stored in Exchange EDB files and granular Exchange user mailbox backup has become a rather difficult task. To backup mailboxes in such scenarios, your best bet is to convert EDB to PST.

First let us look at the differences between EDB and PST files and then we’ll walk through some of the methods that one can use to Convert EDB files to Outlook PST file.

Main difference between EDB and PST files

EDB – It is the Exchange database file that is used by Microsoft Exchange server to store all the information in the Exchange mailboxes such as email, calendar, notes, tasks, contacts etc. The EDB file makes use of a b-tree structure and the data is accessed using Microsoft’s ESE (Extensible Storage Engine). Dismounted EDB files cannot be opened directly.

PST – PST or Personal Storage Table is a database used by Microsoft Outlook for storing data items such as mails, calendar, contacts and other information associated with the Outlook user profile. The PST files and its contents can be opened and accessed easily in various Outlook versions.

Some of the reasons to perform EDB to PST conversion

  • Recover all the information from a corrupted or inaccessible EDB file
  • Save storage space by creating PST archives of large size mailboxes.
  • Granular Exchange mailbox backup.
  • Have local copy of mailbox data backed up for legal or compliance requirements
  • Move mailbox data to another place
  • Retrieve Exchange EDB data from common errors such as JET errors or dirty shutdown
