Configure options through the registry

You can configure some G Suite for Microsoft® Outlook® (GSSMO) features by modifying the Windows registry. This needs to be done on each computer where you want the new setting to take effect. Users can do this themselves if they're comfortable with working in the registry. Otherwise, you, the domain administrator, should make these changes for them.

How do I modify the registry?

In each set of instructions on this page for modifying the registry, you're given a key, a value name (DWORD value or String value), and value data. You must open the registry, create or locate the key, create a value for the key, then modify the value with data. Here's how you do it:

Open the registry

From the Windows Start menu, click Run, then enter regedit in the Run dialog.

If you're using a 32-bit version of Outlook on a 64-bit version of Windows, enter %systemroot%\syswow64\regedit in the Run dialog.

Locate a key

Navigate to the key via the folders at the left of the registry, following the path given in your instructions. The path begins with HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER.

Create a key

  1. Navigate to the folder where you're instructed to create the key.
  2. Click Edit and then New and then Key. This creates a new folder in the folder you navigated to.
  3. Type the key's name as given in your instructions, and click Enter.

Add a new value to a key

  1. Select the key's folder.
  2. Choose Edit and then New and then DWORD Value (to add a DWORD value) or String Value (to add a String value).
  3. Enter the value's name as given in your instructions and click Enter.

Modify value data

  1. Right-click the new value's folder and click Modify.
  2. Under Value Data, enter the value as given in your instructions.
I'm running a 32-bit version of Outlook on a 64-bit version of Windows

If you're running a 32-bit version of Outlook on a 64-bit version of Windows, make all your GSSMO registry settings in the correct location for 32-bit applications. There are 2 ways to do this:

  1. When opening the registry, enter %systemroot%\syswow64\regedit (instead of regedit) in the Run dialog. This opens the 32-bit version of the registry. Then modify keys exactly as described in the instructions given for each setting.
  2. Open the regular registry by entering regedit in the Run dialog. Then navigate to each registry key in its Wow6432Node location for 32-bit applications.

    For example, instead of navigating to HKEY_CURRENT_USER\Software\Google\Google Apps Sync, navigate to HKEY_CURRENT_USER\Software\Wow6432Node\Google\Google Apps Sync.
