Apart from Office 365, the tool performs the migration of Exchange and hosted Exchange data. It conducts various migrations like Exchange to Office 365, Exchange to Exchange, and Office 365 to Exchange, for hosted and on-premises deployments.
To automate the migration of multiple mailboxes, you should use a CSV file and enlist the mailboxes in it. It will save you from inputting the credentials of Office 365 mailboxes manually. The process is quite easier and quicker.
The tool migrates mailbox items to their specific folders, like emails will go to emails, contacts will go to contacts, and notes will go to notes. However, there is a unique feature in the Filter page where you can choose an option to save all data hierarchy into a new folder.
The too provides a sample CSV file on the Home page which you can download, and it has following columns which you need to fulfill -
  • Source Office 365 or Exchange Mailbox
  • Source Login Account(
  • Source Password
  • Source Server name (retain the default value for Office 365)
  • Destination Office 365 or Exchange Mailbox
  • Destination Login Account (
  • Destination Password
  • Destination Server name (Leave it blank for Office 365)
There is a special option on the filter page where you can check the option to exclude the empty folders and the tool will skip all the empty folder automatically.
Mapping is an important activity. If you do not map the mailboxes, then the tool will show error. You have to map the mailboxes and perform the migration again.
