Sign in to the SharePoint admin center with your admin credentials.

Go to Policies > Sharing.

Under External sharing, drag the SharePoint slider down to New and existing guests. (The OneDrive slider is dependent on SharePoint and will also be set to New and existing guests.)

Under More external sharing settings, check the box Allow only users in specific security groups to share externally and select Manage security groups.

Add the security groups that contain the users who are allowed to share content with guest users. You can also create a new security group if needed.

Click Save to apply the settings.

Expand External identities, and then select External collaboration settings.

Under Guest invite settings, choose Only users assigned to specific admin roles can invite guests.
