Convert EDB to PST Format by using ExMerge.exe Utility

EDB to PSTIn my previous posts, I’ve already discussed Microsoft Exchange Server and its file called Exchange database (EDB). Sometimes you may need to import your mailbox content from EDB to PST file. But it’s not at all easy because Microsoft Exchange Server stores mailbox content in EDB files and Microsoft Outlook client doesn’t support this format. In such a situation, the only possible way to import email messages from Exchange to Outlook is by converting EDB to PST format. But if you’re looking for a free solution, you can use the ExMerge.exe utility that can export email messages to Outlook from Microsoft Exchange Server.

The truth says that you can’t import the email messages from Exchange to Outlook directly as it may harm your files or you may lose your data. Now the question arises here how to do that. Generally, people recommend 3rd party paid software utilities for converting EDB to PST format. Such professional solutions are extremely effective. But most of the users are not much interested in paid solutions. Around 60 to 70% users always look for free solutions or any manual approach that requires no cost.

ExMerge.exe Utility by Microsoft

Microsoft provides you a freeware tool, called the ExMerge.exe utility that can handle issues which take place in Microsoft Exchange Server database. The primary function of this utility is to take out the emails from normal as well as corrupt EDB files of Microsoft Exchange Server and save them into PST file format of Microsoft Outlook. Some advantages of ExMerge.exe utility are:

  • You can use ExMerge.exe for single mailbox, multiple or all the mailboxes stored in the Microsoft Exchange Server;
  • It can be used to import data from PST files to Microsoft Exchange Server;
  • Also, you can avoid duplicate messages. The ExMerge.exe utility can help you avoid exporting the same content of a mailbox twice to the same PST file.
  • It can be used as a “brick-level backup” solution that backs up a single mailbox instead of an entire database.

To convert EDB to PST, start with ExMerge.exe installation

To install the ExMerge.exe utility on your system, you must have Microsoft Exchange Server 2003 installed on your system along with the admin tools of Exchange 2003. First, you need to download the ExMerge.exe from the Internet. Click on the ExMerge icon shown below to go to the download page:

ExmergeOn the download page, click on the Download button to start downloading the executable file. Once the executable file (.exe) is downloaded successfully, install it by running it as administrator and then configure it. Once it is configured on your system, log in to your Microsoft Exchange Server account with Exchange Administrator rights.

Things you need to know before using ExMerge.exe: 

  • Make sure you must have full permissions on all the selected mailboxes to be merged. 
  • Besides this, make sure that the computer in which you’re going to run the ExMerge.exe utility, has Microsoft Outlook Client and Microsoft Exchange Administrator programs installed. As Microsoft doesn’t support installing Microsoft Exchange Server components and Outlook on the same computer, you shouldn’t install Outlook on the Microsoft Exchange Server.
  • Being an Exchange administrator, you would have no rights to open the mailboxes if you’re using Microsoft Exchange Server 2000. To overcome this issue, go to the Security tab of the mounted mailbox store in the recovery storage group. You will find the Exchange Administrators Group with explicit deny rights for “send as” and “receive as”. Overwrite it to give them full access and inherit the rights down to each mailbox itself.
