We all know that OneDrive and SharePoint provide a rich set of solutions for collaborating with users both inside and outside of your organization.
External Sharing in SharePoint: –
SharePoint Online has external sharing settings at both the organization level and the site level (previously called the “site collection” level).
There are basically 4 ways by which you can share your content in SharePoint Online:-
a) Anyone – A transferrable, revocable secret key (transferrable means can be forwarded to others, revocable means access can be revoked any time and secret key means users need the link to gain access )
• We can allow some recipients who don’t want to authenticate. If you allow “Anyone” links, invitations aren’t sent an email. Users can copy the link and share it however they like. Anyone with the link (inside or outside your organization) can access files and folders without having to sign in or provide a code. These links can be freely passed around and are valid until the link is deleted or expires (if you’ve set an expiration date).
b) People in your organization – Only grant access to internal users
• To allow external sharing on any site, you must allow it at the organization level. You can then restrict external sharing for other sites. If a site’s external sharing option and the organization-level sharing option don’t match, the most restrictive value will always be applied.
c) People with existing access
• The external sharing features of SharePoint Online let users in your organization share content with people outside the organization (such as partners, vendors, clients, or customers).
d) Specific people
• When users share with people outside the organization, an invitation is sent to the person in email, which contains a link to the shared item.
Authenticated External user and Anonymous user Sharing options: –
Below table gives the difference between functionalities of Authenticated External user and Anonymous user:-
|Authenticated External User||Anonymous User|
|Particularity||Signing in is required before they can view content||Can access content from a shared link without signing in|
|What you can share||• A complete site
• Lists and Libraries
• Documents and list items
• Yammer threads
• Depending on permissions, most content within an Office 365 Group
|Only documents or folders||Who can share||•Site owners and others with full control permissions can share a site
• All members as contributors can share lists, libraries, and documents
• All members can nominate a person to be added in an Office 365 Group as a guest user
|All site users can share a document and generate a view or edit link for external sharing||How you can share||The same as with your internal users||• View only link
• Edit link
|The security risks||• If you give full control to an external user, he could share content with other external users|
• It’s hard to link the email address you sent the invite to and the Microsoft account associated to the user.
• Permission inheritance if you give access to a site or a Group
|Anonymous guest links can be shared to other people who might be able to view or edit the content.

Scenarios of external sharing: –
NOTE: You can stop sharing with guests by removing their permissions from the shared item, or by removing them as a guest in your directory.
External Sharing Configuration in SharePoint
Before managing External Sharing for SharePoint, you will have to make sure it is enabled for your Office 365 tenant as a whole. Below are the steps to enable external sharing in Office 365 tenant: –
