then name your individual folders:
Allow Read and Write permissions on each individual PST file so that the utility can write migration-related metadata to those files.
Note: If you are using an exported or archived PST file, it is not possible to identify the primary root folder for Calendar and Contacts. Therefore, all calendars are migrated as “additional calendars” into Google Apps Calendar, instead of any default calendar. You can avoid this by using PST migration for mails only, and use Exchange server migration for migrating calendars.
