Step 2: Install GWSMO

Users in your organization who want to sync their data between Google Workspace and Outlook must have GWSMO installed on their client computer. There are 2 options for installation.

Option 1: Push an MSI file to your users

1. Download the MSI file from the GWSMO download page.

   Use the correct edition (32 bit or 64 bit) for your users' version of Outlook.

2. Using the software that you use to deploy your organization's applications, push the MSI file to your users.
3. Instruct your users to install the file. Your users can follow the instructions at My admin downloaded GWSMO to my computer.

Option 2: Let your users download & install GWSMO themselves

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

The default location on each client computer is C:\Program Files\Google\Google Apps Sync.

Step 3: Turn on smart features & personalization (Optional)

Step 4: Set up availability information for Exchange (Optional)

You need to take some additional steps if you want your users to be able to query availability information for Exchange users, and you're using GWSMO in a mixed Google Workspace and Exchange environment.

1. Set up Google Calendar Connector Web Service

For instructions on how to install and set up, go to Google Calendar Connector Web Service Installation and Configuration Guide.

Important:

• If your Exchange server is Exchange Online (Microsoft 365), you can't use Google Calendar Connector Web Service.
• When you set up the web service, make sure you do not set up the Google Calendar Connector Sync Service.
• Google Support cannot assist with troubleshooting your Google Calendar Connector Web Service installation.

2. Create a registry key

On each computer that has GWSMO, create the following registry key and string value. If you're running a 32-bit version of Outlook on a 64-bit version of Windows, make sure you create the registry key in the correct location for 32-bit applications. For instructions on using the Windows registry, go to Configure 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>
