Extract EDB to PST

MS Exchange databases are liable to get damaged or inaccessible due to frequent Exchange server failures. Sometimes the Exchange server is made offline and subsequently, all mailbox items in the EDB file become inaccessible. Even, at times, you need to separate/extract only one or a few user accounts. In these circumstances, it becomes crucial to extract user mailboxes from the EDB file andl restore them as PST files, which can be easily imported back into MS Outlook. Moreover, if a situation brings forth the need to convert the EDB file while it is being connected to the Exchange server, you would require performing online EDB to PST conversion.


The Microsoft Exchange Mailbox Merge Program (Exmerge.exe) is an indispensable utility from Microsoft that enables you to backup your Exchange Server mailboxes by extracting data from mailboxes on one Exchange Server and then merging it into mailboxes on another system running Exchange Server. In MS Exchange server 2003, you do not require installing a second Exchange Server environment for restoring a single mailbox or a mailbox item. You can easily restore a user mailbox onto your own Exchange Server by using the recovery storage group. But using ExMerge, one cannot perform conversion of an online EDB file to PST. For the same, you need to take help of an online EDB to PST conversion tool.


Procedure to extract Exchange mailbox using the 'ExMerge' utility in MS Exchange server 2003:

  • First, logon to the MS Exchange Server and start the 'ExMerge' utility. You should have full Exchange Administrator rights to perform this process. To do so, open the 'Security' tab of the mounted mailbox store in the recovery storage group and allow the 'send as' and 'receive as' permissions for the Administrator Group.
  • Specify the name of your MS Exchange server.
  • Choose the appropriate information store database from which you need to extract the mailbox.
  • Select the user mailbox to be extracted.
  • Last, specify the location of the PST file in your system.

However, with MS Exchange server 2003 service pack1, you can use the recovery mailbox center to extract single mailbox. MS Exchange server 2007 uses the Exchange Troubleshooting Assistant (ExTRA) or the Exchange Management Shell (EMS) to create an RSG. Also, it allows restoring multiple Exchange databases to the recovery storage group. MS Exchange server replaced the recovery storage groups with a new concept 'recovery database'.


Sometimes due to incorrect permissions or when your computer is running out of disk space, the 'ExMerge' utility fails to merge the mailbox data into the production database.
