How to enable 3rd party cookies for various browsers - Outlook Plugin integration requirement (FireFox, Edge, Safari)

Certain integrations or embedded features within applications might need to access your email service indirectly to function correctly. Third-party cookies, in this context, are cookies set by a domain different from the one you are currently visiting (the application you are using) but are necessary for seamless interaction with your mail provider. By allowing third-party cookies specifically for your mail provider's URL, you enable these integrations to work as intended without compromising your overall privacy settings.

Enabling Third-Party Cookies for Your Mail Provider in Safari

‍

Follow these steps to allow third-party cookies specifically for your mail provider's URL in Safari:

1. Open Safari.
2. Click on Safari in the menu bar (top left of your screen).
3. Select Preferences.
4. Click on the Privacy tab.
5. Ensure that Prevent cross-site tracking is checked. This is Safari's default setting to block third-party cookies.
6. To create an exception for your mail provider:
   
   • Click on Manage Website Data....
   • In the search bar (top right), type the domain of your mail provider URL (e.g., google.com for Gmail, live.com for Outlook.com, yahoo.com for Yahoo Mail).
   • Select the entry for your mail provider.
   • Click Remove.
   • Click Done.
7. Close the Preferences window.

Safari's approach is slightly different. By removing the existing website data and then interacting with your mail provider again within the application requiring the integration, Safari might prompt you or allow the necessary third-party cookies for that specific session or based on the application's request. If issues persist, you might need to temporarily uncheck "Prevent cross-site tracking" while using the integrated feature and then re-enable it afterward for general browsing. Some applications might also guide you through a specific permission request within Safari.
