Is there a way I can use flow to get approval from users that aren’t in my organisation?

Hi @ JakeGardner,


Starting an approval from users outside the organization are not supported in Microsoft flow currently, If you would like this feature to be added in Microsoft Flow, please submit an idea to Flow Ideas Forum:

Hi, I'm looking for the same option as we need to sen approval for owning company that they are not on the same domain name.

Has the issue been resolved/added?

I take no credit for the below but it may work for external users as that is what I was trying to achive.  But I have not tried it in anger.


If this works then please let me know.  I was given a zip file of the flow, not sure how to get it to you though vai a fourn like this.





Hi, I imported the Flow, definately it is above my level, I'm only a user, but a least I figured out that it create a html with responses sent via email.

I think that "Approval" Flow is more secure to ensure that only the emailed person respond and we capture his response.

I'll wait till Microsoft decide to add External Users to the "Approval" flow.
