External guest users using azure b2b

How does Azure B2B work with the external sharing tenant setting. What will happen if the external sharing option is turned off, but the external users have been added as guest users in the Azure portal?

I don't believe this is properly supported by Power BI at the moment, and the app-owns-data approach is the only way this can be accomplished.


- Because the frontend could be signing in using ADAL with a client id that is different than the AAD Application where the Power BI app is hosted, errors will be given when attempting to get a power bi access token, advising that the user must be added to the tenant where Power BI resides.

- This works as expected if the users are all in the same directory -- but if your audience is in a different directory than your power BI subscription, we ran into errors.

- Even for the same directory configuration, you may have problems with if the user is a guest user. We added a guest user, put them in appropriate Power BI groups, but an InternalServerError was given when attempting to get a Power BI access token. Also noteworthy that will not let you login with personal accounts -- it must be a work/organizational account, which is another reason why guest users may give you problems.

I hope someone from the Power BI team is able to explain how to accommodate B2B and B2C configurations using the end-user's bearer token, instead of the app-owns-data setup.

Hi @mahimabedi


I would think that it would still work, because when they are authenticated the user does exist in AAD.


But it would need to be tested to ensure that it works as expected.

Did I answer your question? Mark my post as a solution!
