About G Suite Migration for Microsoft Outlook

Also known as GSMMO

GSMMO used to be known as Google Apps Migration for Microsoft Outlook (GAMMO). 

G Suite Migration for Microsoft Outlook (GSMMO) is a utility that lets Microsoft Outlook users import existing mail, calendar events, and personal contacts from a Microsoft Exchange account or PST file into any G Suite account. You can set up and run your migration by stepping through an easy-to-follow wizard. You can also run the utility as a command-line tool.

With GSMMO, you can:

  • Import mail, calendar, and contact data, either all at once or in separate stages
  • Import only mail sent before or after a specific date
  • Skip importing junk mail and deleted items
  • Exclude specific mail folders from being imported (requires running the command-line utility)
  • Monitor the progress of your migration
  • Easily pause and resume the migration
  • Run subsequent migrations that import only new data (avoiding data that's already been imported)

Note: GSMMO imports only your personal contacts, not your organization's Global Address List. Your domain administrator imports the global addresses with a utility such as Google Cloud Directory Sync.
