ExMerge has been around for a long time, its used (as the name implies) to merge pst files into existing mailbox’s. However its also a great tool to export/backup users mail box’s if you’re doing a migration, or if you have got your “Disaster Recovery” hat on.
The following is a run through of how to export from a mail store to pst files – Note on a live system this can take some time, the example below was done in VMware on a test Exchange box that had 1000 users (as it was a test server the mailbox’s were tiny) If you need to do this on a production server plan in a LOT of time if your moving a large amount of data.
Note: I’ve mentioned it in the video, but just to reiterate, your mailbox’s need to be smaller than 2GB, if that can not be achieved, you can either;
1. Use ExMerge and export particular “date ranges” and produce multiple .pst files for the same mailbox (hopefully less than 2GB).
2. Use Outlook 2007 (or greater) to export the mailbox to .pst files individually.
