This page is for administrators who plan to deploy G Suite Migration for Microsoft® Outlook® (GSMMO) to their users.

If you are a user that wants to install and use GSMMO,  you should instead see GSMMO user help.

Overview

GSMMO lets individual users migrate their own email, calendar, or contact data from Microsoft Exchange or from local personal storage table (PST) files to a G Suite account. Administrators can use the command-line version of the utility to migrate data on behalf of a single user.

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 has to migrate the data first with a utility like Google Cloud Directory Sync.

Operating system and Outlook requirements for client machines

Note: As the platforms are no longer actively supported by Microsoft®, support for Windows® XP and Server 2003 was discontinued on December 31, 2018. Learn more.

Each user's machine that runs the migration utility needs to have the following minimum configuration.

Operating system requirements

  • Windows Vista (32 bit) SP1 
  • Windows Vista (64 bit) SP1 
  • Windows 7 (32 and 64 bit)
  • Windows 8 (32 and 64 bit)
  • Windows 10 (32 and 64 bit)

Note: Regardless of which version of Windows you are using, we recommend that you upgrade 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 Outlook 2003 and Microsoft Outlook 2007 are no longer actively supported by Microsoft. We recommend that you upgrade to a supported version of Microsoft Outlook.

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 any G Suite administrators, must also sign in to their G Suite account at least once, to accept the Google Terms of Service.

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
(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, see:

Install G Suite Migration for Microsoft Outlook

After you have configured G Suite, verified the Windows system requirements on each client machine, provisioned your users in G Suite, and migrated your shared contacts, your next step is to install GSMMO on each user's computer.

You have two options for installation.

Option 1: Push an MSI file to your users

Push an .msi file to your users, and let them use the Run Advertised Programs option in the Windows Control Panel. Download the .msi file below (be sure to pick the correct version for your users' version of Outlook). For information on implementing the .msi file, consult your Microsoft documentation.

Option 2: Let users download GSMMO themselves

Users can download the utility from the GSMMO download page. To install the plugin, they can then follow these instructions.

To run the installer:

Double-click OutlookMigrationSetup.exe, then click Run.

The utility is installed in the following location:
C:\Program Files\Google\Google Apps Migration\ClientMigration.exe

Perform migrations

Run only one instance of the utility on a computer, and run only one instance of the utility for each user.

For detailed information about using the utility to perform migrations, see GSMMO user help.
