My organization uses Office 365 for email distribution lists and to host an internal SharePoint site for document storage.
We currently use distribution list Groups to host the email lists. I now want to give the same external users the ability to log into the SharePoint site (as external users, without licenses).
I would ideally use a single Distribution List or Mail-enabled Security group to grant both email list and SharePoint access via a single Group. However, that appears to not be possible.
Instead, I've created a new Security Group to mirror the list of external users. I've added my personal email as a member of this group.
Opening the SharePoint site, I press "Share" and the Security Group autocompletes in the list.
After sharing, the Security Group appears in the "Shared With" list:
So, this all appears to be working within the Sharepoint / Office 365 interface.
But, my personal email never receives an invite to the SharePoint or any mail at all.
When I try to access the Sharepoint via URL, I log in with my personal Microsoft account using the same email that is added to the Security Group.
That gives the error:
That didn't work
We're sorry, but yourEmail@example.com can't be found in the yourDomain.sharepoint.com directory. Please try again later, while we try to automatically fix this for you.
Why isn't this working?
How can I create a Group of people, and add all of them to the Sharepoint as external users?
Bonus points if a single list of email addresses can be used for both the email distribution list and for the Sharepoint access.
NOTE: I'm unable to use the new "Office 365 Groups" for this as those have other undesirable behaviors. Namely, generating a new, unneeded SharePoint site for the Group and allowing users to unsubscribe from the Group's emails.
