Set up GWMMO (for admins)

This article is for administrators setting up GWMMO for their users. If you're a user, go to Download & install GWMMO .

You can set up Google Workspace Migration for Microsoft Outlook (GWMMO) for users in your organization so they can import their own email, calendar, and contact data from a Microsoft Outlook account or PST file.

Step 1: Set up your users in Workspace 

Before your users can migrate data, you have to set up accounts for them in Workspace. You can re-create aliases that users had on your Exchange server and create groups that match your Exchange mailing lists. For details, go to Add an account for a new user .

Step 2: Decide about smart features & personalization

Step 3: Migrate your shared contacts (Optional)

Before your users migrate their data, you can optionally synchronize your organization’s shared contacts to Workspace using Google Cloud Directory Sync (GCDS). Doing so lets your users have immediate access to your organization's full address list.

For information about syncing contacts, go to Google Cloud Directory Sync .

Step 4: Install GWMMO

You should use only one instance of GWMMO per user.

Option 1: Push an MSI file to your users

3. Instruct your users to install the file. Your users can follow the instructions at My administrator downloaded GWMMO to my computer .

1. Instruct your users to download the Recommended for usersEXE file from the  GWMMO download page .
2. Your users can complete the installation by following the instructions at I'm downloading & installing GWMMO myself .

Step 5: Instruct users to import their data
