G Suite Migration for Microsoft Outlook

This article is for G Suite administrators. To begin using GSMMO, go to GSMMO User Help.

You can set up G Suite Migration for Microsoft Outlook (GSMMO) for users in your organization so they can import email, calendar, or contact data from a Microsoft Exchange account or PST file.

Overview and system requirements

Overview

GSMMO lets individual users migrate their own email, calendar, or contact data from Microsoft Exchange or from local PST files to a G Suite account. Administrators can also use the command-line version of the product to migrate data on behalf of a single user. Learn more

Note: Only personal contacts are migrated for each user. In order for your Global Address List, including shared contacts, to be available to users, an administrator must migrate the data first with a utility like Google Cloud Directory Sync (GCDS).

Operating system and Outlook requirements for client machines

Note: As Microsoft no longer actively supports the platforms, support for Windows XP and Server 2003 in our data migration and sync products was stopped on December 31, 2018. Learn more

Each client machine that runs the migration utility needs to have the following minimum configuration.

Operating system requirements

  • Windows Vista (32 and 64 bit)
  • Windows 7 (32 and 64 bit)
  • Windows 8 (32 and 64 bit)
  • Windows 10 (32 and 64 bit)

Regardless of which version of Windows you're using, we recommend you update to the latest patches for that version.

Note: GSMMO isn't supported for Apple® Mac®. To synchronize a Google Account with Outlook for Mac, consult your Microsoft documentation.

Outlook requirements

  • Microsoft Outlook 2003 SP3 
  • Microsoft Outlook 2007 SP2 (or SP1 with hotfix)
  • Microsoft Outlook 2010 (32 and 64 bit)
  • Microsoft Outlook 2013 (32 and 64 bit)
  • Microsoft Outlook 2016 (32 and 64 bit)
  • Microsoft Outlook 2019 (32 and 64 bit)

Note: Microsoft no longer actively supports Outlook 2003 and Outlook 2007. We recommend you upgrade to a supported version of Microsoft Outlook.

Set up and install GSMMO

Step 1: Provision your users in G Suite

Before your users can migrate data, you have to provision accounts for them in G Suite. Learn more

Each user, including G Suite administrators, must also sign in to their G Suite account at least once, to accept Google's Terms and Conditions.

In addition to provisioning user accounts in G Suite, you can also:

  • Create nicknames for your users that match aliases they had on your Exchange server
  • Create groups that match the mailing lists on your Exchange server
  • Add domain aliases
Step 2: (Optional) Migrate your shared contacts

Before your users migrate their data, you can migrate your shared contacts to G Suite so your users have immediate access to your full address list.

For information about migrating contacts, go to:

Step 3: Install G Suite Migration for Microsoft Outlook

After you’ve completed the steps above, your next step is to install GSMMO on each client machine.

There are 2 options for installation.

Option 1: Push an MSI file to your users

To do this, download the MSI file from the GSMMO download page. Be sure to pick the correct edition (32 bit or 64 bit) for your users' version of Outlook.

You can then push the MSI file to your users with the software you use to deploy and safeguard your organization's applications.

Your users can then follow these instructions to install the file.

Option 2: Let your users download and install GSMMO themselves

Your users can download the EXE file from the GSMMO download page.

They can then follow these instructions to install the file.

Install location

The default location on each client machine is C:\Program Files\Google\Google Apps Migration.

Import data

Run migrations

Run only one instance of the utility on each client machine, and run only one instance of the utility for each user.

For detailed information about using GSMMO to run migrations, go to GSMMO user help.
