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 Outlook as one or more PST files and then import those files.

You're on step 3 of 5

Choose where to import your data from

• If your existing profile is listed, choose its profile name to import directly from the profile. GWMMO copies the profile's current data and imports it.
• If you 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. GWMMO needs write permission to access your data.

Migrate all or new data

1. Choose your migration option:
   • 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 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 your Google Workspace account, choosing this option duplicates contacts and overwrites your existing calendar data (email won't be duplicated).

   • Migrate only new data—Imports 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 or to import data that arrived after your first migration.
