One of the most common bulk provisioning techniques used in the Exchange Management Shell makes use of comma-separated value (CSV) files. These files act sort of like a database table. Each record in this table is represented by one line in the file, and each field value is separated by a comma, which is used as a delimiter. In this recipe, you'll learn how to set up a CSV file and create recipients in bulk using the Exchange Management Shell.
In addition to the Exchange Management Shell, you'll need to use Microsoft Excel to create a CSV file.
