SharePoint Permission for guest users through security groups

I noticed something strange in SharePoint Online and would like to get your confirmation for this behaviour or your comment if I am doing anything wrong.

 

We have many guest users in our organisation and some of them need access to SharePoint. This access can be given if I add those users in the library settings explicitly:

 

- The site has guest sharing enabled
- The guests are already added in our AD (existing guest users)
- The library has unique permissions

This works as expected and guests can access. 

But if I add those guest users to an AAD security group (not a SharePoint group) and add the group in this list, they always get this screen here:

This is an issue, because we are using security groups in many libraries and adding users manually is a huge pain... do you have any suggestions?
Are guest users from security groups not synced in the corresponding SharePoint groups?

    Do you add the AAD group inside an existing sharepoint group or directly in root site permissions? This procedure you are describing we're using a lot since we also use dynamic group membership to populate those guest accounts and then add those dynamic groups to sharepoint. So from what I can understand this should work as you want.

      Sorry for the late reply. I didn't see the notification.
      I am adding the AAD group in the site visitors group.
      The site visitors group is a SharePoint group, but I do not use dynamic groups.

      However, an external user does not get access to the site through a group. Only throug a direct user assignement. Any further idea? That is an important issue for us...

        Also: When I "check permission" I receive none as a result 😞

      No, I could not find a solution.. maybe just not supported to allow external users access via groups 😞
