Add users to a SharePoint Online Site
Adding members to a Sharepoint site is necessary so they can have access to that site and its information. Upon creating a new user and assigning a Sharepoint license, the user will be able to access Sharepoint, but will only see public sites. See below for instructions on how to add a user to a Private Sharepoint site.
1. Log in to SharePoint Online with administrative credentials. Then, go to the SharePoint admin center and under Active sites, click on the desired SharePoint site.
2. Click the gear icon and click Site permissions.
3. The Site permissions dialogue box will get open. Here, click the Invite people option and choose "Add members to group" then "Add members".
4. Here, you can search and add users, Office 365 groups, or security groups for providing access to the selected site.
Note: If the site is part of the Office 365 group, so the added users would get access to this Office 365 group site only and not to other Group resources (calendars and conversations).
5. Once desired users are selected for adding to the SharePoint Site, click Add.
6. The users will get successfully added to the SharePoint Site. You can decide which permissions to be assigned to the added users (at first, they are Site visitors by default).
- Users with Edit permissions are shown under Site members.
- Users with Full control permissions are shown under Site owners.
