Users who want to sync their data with Outlook must have GSSMO installed on their computer. You have 2 options for installation.

Option 1: Push an MSI file to your users

To do this, download the MSI file below. Be sure to pick the correct one, which is based on your users' version of Outlook.

• 32-bit enterprise_gsync.msi (Outlook 32-bit editions)
• 64-bit enterprise_gsync.msi (Outlook 64-bit editions)

Your users can refer to I'm installing GSSMO myself for further instructions.

Option 2: Let users download GSSMO themselves

Users can download GSSMO from the GSSMO download page. They can then follow these instructions to install the plugin.

If you're using GSSMO in a mixed G Suite and Microsoft Exchange environment, and you want to query availability information for Exchange users, you need to:

1. Install and configure Google Calendar Connector Web Service. For instructions, see Google Calendar Connector Web Service Installation and Configuration Guide.

   Important: When you set up the web service, make sure you don't set up the Google Calendar Connector Sync Service.

2. Create the following registry key and accompanying string value on each computer where GSSMO is installed. If you're running a 32-bit version of Outlook on a 64-bit version of Windows, create this registry key in the correct location for 32-bit applications. For details, see the instructions on using the Windows registry at Configure limits and options through the registry.
   • Registry key— HKEY_CURRENT_USER\Software\Google\Google Apps Sync\CalendarSync
   • String value—Value name: FreeBusyURL; Value data: <URL for the Calendar connector>

     Example
     http://www.MY_COMPANY_FREEBUSY_SERVER.com/GCalExchangeLookup/ExchangeQuerier.aspx (where you replace MY_COMPANY_FREEBUSY_SERVER with the name of your company's server)

Note: Google Support cannot assist with troubleshooting your Google Calendar Connector Web Service setup.

With GSSMO, your users can import data from an Exchange account or Outlook PST file. To do this, GSSMO uses a separate migration tool, G Suite Migration for Microsoft Outlook (GSMMO). GSSMO launches the migration tool automatically and, in most cases, users won't even notice they're using a separate tool.

GSSMO launches the migration tool when the user:

• Imports data when they create or make another user profile. See Create or replace your GSSMO profile.
• Imports data after they create their profile. See Import data to an existing profile.

G Suite Migration for Microsoft Outlook as a standalone migration tool

Users can launch G Suite Migration for Microsoft Outlook as a standalone application by going to the Windows Start menu and clicking G Suite Migration for Microsoft Outlook.

However, this doesn't import Outlook notes, tasks, or journal entries. To import this data, users should run their migrations using GSSMO.

Users can import mail, contacts, calendar events, and Outlook notes, which are then available in Outlook and the G Suite web interface. They can also import Outlook tasks and journal entries, which remain available only in Outlook.

The G Suite Migration for Microsoft Outlook tool must be installed on each user's computer.

Users who download GSSMO from the download page will install the migration tool automatically. If you push GSSMO to users via an MSI file, you need to push the migration tool to them as well. Or, have them install the migration tool themselves. For details, see Install G Suite Migration for Microsoft Outlook.
