Giving intranet site access to external guest users

[origami]

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:
   https://[TenantName]-admin.sharepoint.com/_layouts/15/online/AdminHome.aspx

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:

5. Click Edit on [External sharing]

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