Using ExMerge to migrate EDB to PST

 

The Exchange server database contains emails, contacts, calendar items, journal etc of exchange account users. This data is stored in files with the extension EDB. As with any other files or database, EDB files are prone to corruption. When this happens, user access to data through Exchange accounts gets barred and they face error messages. In such a case, some help is needed to access the data in the corrupted EDB files. This help comes in the form of automated tools. Such tools can not only recover data from corrupted EDB files but also migrate all EDB data to PST data. Hence, users can access their Exchange server account data on their desktop/laptops through Outlook. A variety of EDB to PST migration tools is available online. One such great tool is the ExMerge Utility developed by Microsoft.

ExMerge Utility

The ExMerge Utility basically provides merger of Exchange server mailboxes. It extracts data from mailboxes on one Exchange server and then merges it into mailboxes on another Exchange Server. It also performs the task of copying data from a source Exchange server file (EDB) into a PST file (MS Outlook archive file) and then merge the data in the PST file into mailboxes on the destination server. This ability to merge data among Exchange server mailboxes makes it a competent tool to consider for recovering from disasters like corruption.

Limitations of ExMerge

Though the ExMerge Utility is a one step solution for migrating safely from EDB files to PST files, it has some limitations. Following are some of the points where ExMerge fails to impress:

ExMerge cannot work with mailbox sizes greater than 2GB

If the Exchange server itself is corrupted, ExMerge will fail to operate

Since it does not have a mailbox store, this utility cannot be used on front-end servers

It works only with a private folder on Exchange server. Public folders are not supported

If the permissions are not correct, ExMerge fails to extract data. However, this limitation can be overcome by creating a new service account.
