To share a result within your team or perhaps in your portal you open the results in Answers > All questions. When the results are showing, simply click on the share button in the right bottom corner and share.
The live link enables you to share the results using the URL and can be useful if you would like to share a result via email, to your intranet, a public screen or other devices.
Decide what setting to have under "The link should only work for" and select what period you would like to show. Due to security reasons, the maximum number of days to have the link open is 14 days.
The intended usage of the sharing is that you either generate a time-bound link, or you generate a "forever-working" link but in that case, to ensure that the link doesn't get spread to the wrong people, you have to set an IP address. You can add multiple IP-addresses separated by a comma, but it does not accept wildcards at the moment.
Please note that the link will show the results for the question that you share, and not all the results of a pulse.
