how to block gmail access to my contact lkist

To block Gmail access to your Outlook contacts list, you can use Group Policy settings to manage the synchronization of contacts. Specifically, you can enable a policy that blocks synchronization of contacts between Outlook and social networks, which includes Gmail. This is done by setting the DisableContactDownload policy to 1. Here are the steps:

1. Open the Group Policy Editor.
2. Navigate to the following registry key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\Outlook\SocialConnector.
3. Create or modify the DWORD value DisableContactDownload and set it to 1.

This will prevent Outlook from synchronizing contacts with Gmail, effectively blocking access to your Outlook contacts list from Gmail.

Dear @Laurence Steinberg, 

Good day! Welcome to Microsoft Q&A forum! 

Based on your description, I understand that you want to prevent Gmail from accessing your Outlook contacts and are seeking guidance on how to block this integration.

To understand the situation better and provide you with the most suitable support, could you confirm the following information: 

• Do you currently have your Gmail account connected to Outlook?
• Do you want to completely stop Gmail from syncing contacts with Outlook, or just pause it temporarily?
• Do you use Gmail for sending/receiving emails in Outlook, or only for contact sync?
• Is it okay with you to revoke Google’s access to your Microsoft account?
• Do you want to enforce this restriction through Conditional Access policies in Microsoft Entra ID, so that Gmail access via web browsers is blocked while desktop Outlook remains allowed?

Your confirmation would be very helpful in ensuring you receive the most suitable support!

If you’re able to share a bit more about your situation, I might be able to suggest some helpful next steps. 

Kindly let me know when there are updates or if you need further assistance. Any updates you’re able to share would be really helpful. I appreciate your time and look forward to hearing how things are going!
