How to Give External Users Access to SharePoint Online

For two decades, SharePoint has been the collaboration system of choice for companies around the world. The platform's advanced capabilities create a secure environment for information exchange, data recording and document sharing. The sharing feature in SharePoint enables you to open SharePoint files even if you are not a regular user. In this article, we'll describe how to share with external users to the file types that can be included.

Depending on how external sharing of SharePoint is configured, users have several different options when deciding to share with people outside their organization. Users can:

1. Share a SharePoint document or folder.

2. Share a SharePoint site.

Also, before you start sharing, you need to make sure your sharing settings are set up correctly. SharePoint allows you to control these both at the organization level and at the site level. For users to be able to share content at the site level, external sharing must be enabled at the organization level.

Step 1. Go to Sharing in the SharePoint admin center and login with an account that has administrator rights to your organization.
Step 2. Under "External Sharing", specify the sharing level for SharePoint and OneDrive. The default level for both is "Anyone".

The main difference is that once they accept the invitation, they will also receive group emails, calendar invitations, and Yammer discussions. They'll also gain access to the group's associated SharePoint team sites and content.

By default, anyone in your organization can add guest users to Microsoft 365 groups. But permissions and access differ between group owners, group members, and group guests.
