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. Sometimes you may need to import your mailbox content from Exchange EDB to PST file. There could be many reasons why you would want to export mailboxes directly from the Exchange Server to PST. You may be updating your hosted Exchange environment or you could be moving to a different Exchange organization. This help comes in the form of automated tools. Such tools can not only export data from EDB files to PST but also migrate all EDB data to Live Exchange Server and Office 365. Subsequently, users can access their Exchange server account data on their desktop/laptops through Outlook. A variety of EDB to PST migration tools are available online. In fact Microsoft also offers one such great tool - ExMerge Utility.
The ExMerge.exe 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
- 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.
- If User is using Exchange Server 2007 then ExMerge fails.
- ExMerge is a lengthy and time consuming utility.
- Risk of data loss.
