Giving intranet site access to external guest users

When trying to share your intranet site with external users/ guests, you might run into the following error:

Your organization’s policies don’t allow you to share with these users. Go to External Sharing in the Office 365 admin center to enable it.


Here is how to fix it:

  1. Navigate to your tenant admin home:

  2. Click Sites -> Active Sites

  3. Pick the site you would like to enable for external sharing

  4. In the flyout window select the policies tab:


  1. Click Edit on [External sharing]

  2. Set the [New and existing guests]. Here you can optionally limit the domain names that can be added as guests if you need.
