Setting Permissions for Merging Data

Before you can insert data back into the original mailboxes, you must override the default administrative permissions denials on the target database.

By default, Windows accounts with administrative access are denied permission to read the content of ordinary Exchange mailboxes. For ExMerge to merge data with the original database, it must be able to open mailboxes in that database. Therefore, ExMerge cannot be used for this purpose by an administrator without first overriding the permissions denials.
