How to migrate EDB to PST with the help of ExMerge Utility
Microsoft has offered ExMerge utility in order to handle problems that occur in the database of Exchange server. ExMerge utility has been designed to extract emails from a corrupted Exchange server, save it in .PST file and place it at desired storage location. Outlook PST (Personal Storage Table) is a file format that contains copies of windows messaging, calendar entries, e-mails and other items supported by Microsoft Exchange. ExMerge is useful to avoid virus attacks as it has the capability to find and extract a specific e-mail message from infected EDB.
ExMerge utility can be applied for a single mailbox, chosen mailboxes or all mailboxes in an Exchange server store. Including this, it can also process a batch of .PST files, matching them up correctly with Exchange mailboxes while importing data from .PST files to an Exchange server. ExMerge is advanced about duplicating messages as it prevents you from exporting the same contents of a mailbox twice to the same .PST file. Another advantage of this outstanding duplicate detection is that you can use ExMerge as a "brick level backup" solution which is backup of a single mailbox instead of an entire database.
For installing ExMerge utility, you must have Exchange server 2003 (along with admin tools of Exchange 2003). The supported versions of Exchange server are 2003, 200 and 5.5 & supported operating systems include Windows 200 SP3, Windows server 2003 and Windows XP. However, MS Exchange server 2007 doesn’t permit ExMerge utility to be run directly on the Exchange server machine which is possible with the earlier Exchange versions. On the other hand, this utility takes many steps & more time to run. Usually, it consumes 45 minutes as the average time the initial step takes around 45 minutes for a single GB of EDB data.
Furthermore, ExMerge can take one to two hours for the execution of the second step of the process. So, you should plan carefully before you actually apply this utility on corrupt Exchange database. In case, you do not get satisfactory result from ExMerge utility, you are recommended to look for a third party tool like Kernel for Exchange server recovery. It is a trustworthy & proficient EDB recovery tool and it easily resolves all issues of Exchange server and finally converts inaccessible EDB files into Outlook PST format.
