    We have been having issues where the "guest User" can no longer log into our tenant. The only option is to remove them from Contacts, and everywhere else in the tenant. E.g, SharePoint Sites, user profiles, Azure AD, Azure AD deleted users, all the hidden Userinformation list in ShaarePoint etc. Then invite the Guest user again. I have had a couple of support calls with Microsoft about this, and the case ends with this information as the resolution:
    "This is behavior by design as all objects in Azure AD have to be unique.
    You cannot have 2 objects with the same email address.

    When you invite one of your contacts to your content in O365, it actually creates a completely new guest user object in your environment and since the email address which is supposed to be populated in the email attribute is already in use by the contact, the email address does not get populated.

    The only way to resolve this issue at the moment is to eliminate any conflicts that are in place, by removing the conflicting email contact and re-invite the user to your content."

    This clearly is a bug where the two parts of Azure get's a conflict, which must flag up in some bit of code, but never flagged up to the Azure Administrator of the tenant.
