How do I grant an external user access to my SharePoint site?

Question

My tenant allows the least restrictive sharing restrictions (anyone).

I have granted access to person@external-domain.net, but when that person tries to log in to my SharePoint site, they still get this error message:

What am I missing? person@external-domain.net shows up as a guest user when I go to the "New Groups" in the "New Outlook," (because adding external users to a SharePoint group has to be done through Outlook) but even though that person shows up as a guest, they're still getting the error shown above.

Is there somewhere else I go to approve access for person@external-domain.net?

Hi,

You need to add to the Sharepoint Resource Group in your tenant. For example, if you have a Sharepoint with name "Financial", it has a 3 groups (visit, owner and members) with differents permissions.

For this, you need to go to the configuration options and check this

And add your user in one of the groups
