SharePoint Online - External Sharing, licensing
Thanks for such a quick reply that's very helpful! Just to clarify, so even with just one E1 license, the number of external users is unlimited?
Christopher,
With an E1 (or any of the E plans) you get unlimited external sharing, so you won't have any limit there.
As far as employees, even if they don't have a company email address you still need to license them. "An external user is someone outside your organization who can access your SharePoint Online sites and documents but does not have a license for your SharePoint Online or Microsoft Office 365 subscription. External users are not employees, contractors, or onsite agents for either you or your affiliates" - https://support.office.com/en-us/article/Share-sites-or-documents-with-people-outside-your-organization-80E49744-E30F-44DB-8D51-16661B1D4232
External Sharing is possible with users of other tenants?
Yes, you can share to any external users of other tenants.
Thank you !!
- and also to users who have a 'Microsoft account' - e.g. a windows live, Hotmail, outlook.com account, etc.
In other words, you can share with people who do not themselves use Office 365.
