Something not right when sharing to outside users

I'm also having problems with sharing my Dashboard with individuals "outside of my organization". The Share button is grayed out until I type an e-mail address, and then it only becomes clickable if the emails are people within my organization.

For people outside of my organization, this error pops up "One or more emial addresses are outside of your organization", and the Share button remains grayed out. 

I'm using the free Power BI service, and I'm sharing to indivdiuals that are also only using the free version. 

New to Power BI.  I am having this same issue and need to discover a solution to support a client's needs. 

Error message I received:

Hey All,

I had a similar issue but was able to resolve it. It's a pretty specific case but may help you find a workaround. Here is a description of the scenario and the workaround. Hope it helps!

Dashboard was loaded to a distinct workspace that was created when the project started. Although I am an admin on this workspace the owner of any given workspace is created using a mock email address of the workspace name and virtualized in Azure AD. PBI allows admins to share dashboards in a workspace but it looks like it actually doesn’t grant access to users outside the organization. In order to get around this I had to give myself direct access to the dashboard with sharing permissions on and then, using the link in the access granted mail, re-grant any outside domain user.

Had the same problem, fixed by adding the administrator as a user; blogged about it here: http://lookatyourdata.co.uk/2017/02/27/power-bi-you-dont-have-access-to-this-dashboard/
