Download, install, and import

3. Choose what Outlook data to import

Next, Google Workspace Migration for Microsoft Outlook (GWMMO) asks you to select where to import data from. You can import data directly from a Microsoft Exchange profile. Or export it first from Microsoft Outlook as one or more PST files, and import those files.

All that's left is selecting what data to import...

  1. Choose where to import your data from, as follows:

    If your existing profile is listed, choose its profile name to import directly from the profile—GWMMO takes a snapshot of the profile's current data and imports just that. If instead you've exported your data to a PST file, choose From PST File(s) and browse to the file on your computer or network. (Control-click multiple PST files to import them all at once.)

    You can't import PST files that are read-only. The migration utility needs write permission to access your data.

  2. If you've already imported data into this account, choose the appropriate migration option, as described below. (If you're importing for the first time, either option works fine):
    • Migrate all data: Imports all your mail, contacts, and calendar events. You can choose this option for your initial migration. Or, choose it if you've deleted all previously imported data from this account (such as after a test migration), and want to import all your data again.
      If you already have data in this Google Workspace account, choosing this option will import duplicate contacts and overwrite your existing calendar data (email won't be duplicated).
    • Migrate only new data: Imports only data that hasn't been imported before (doesn't duplicate contacts or overwrite existing calendar data). Choose this option to resume a migration that didn't fully complete (say, if you had to turn your computer off), or to import data that arrived after your first migration.
  3. Click Next in the wizard to continue.
