#Parameter $AdminCenterURL = "https://crescent-admin.sharepoint.com" $OneDriveHostURL = "https://crescent-my.sharepoint.com" $SharingSettings = "Disabled" # Disabled, ExistingExternalUserSharingOnly, ExternalUserSharingOnly, ExternalUserAndGuestSharing #Connect to Admin Center Connect-SPOService -Url $AdminCenterURL #Set External Sharing settings for an OneDrive site Set-SPOSite -Identity $OneDriveHostURL -SharingCapability $SharingSettings
Enable External Sharing for a OneDrive for Business Site
By default, all existing OneDrive sites inherit external sharing settings from the OneDrive admin center. However, there are times you may want to either enable or disable external sharing for a particular user’s OneDrive for Business site. (Provided you have external sharing enabled for OneDrive for Business at the tenant level!)
- Login to Microsoft Admin Center at https://admin.microsoft.com
- Expand Users >> Active Users >> Search and find the user you want to enable External Sharing OneDrive for Business.
- Click on the User name to open user properties >> Click on the “OneDrive” tab >> Click on the “Manage external sharing” link under “Sharing” (You won’t get this link if external sharing is disabled at the OneDrive Admin center!).
- Tick the “Let people outside your organization access your site” checkbox and choose any of the options as per your requirement.
E.g., Suppose your OneDrive for Business Tenant-wide configuration is set to allow only external users by inviting them to Azure AD. In that case, you can go for the last option, “Only allow sharing with existing guest users in the directory.”
Please note, Since SharePoint and OneDrive products are tightly coupled, and OneDrive is on top of SharePoint Online, External sharing at Individual OneDrive sites can’t be more permissive than the OneDrive for Business external sharing settings configured at the tenant level. E.g., If the external sharing settings at your OneDrive for Business Admin site is set to “Existing external users”, then the settings at your OneDrive site should be “Only allow sharing with existing guest users in the directory” or lesser (External sharing disabled!). Otherwise, You’ll receive an error message, “Update failed for OneDrive external sharing setting. It needs to be more restrictive. Please check the sharing setting under Resources > Sites.”
PowerShell to Enable External Sharing for a OneDrive Site
We can set the external sharing settings at the site level using PowerShell as well:
#Parameter $AdminCenterURL = "https://crescent-admin.sharepoint.com" $OneDriveSiteURL = "https://crescent-my.sharepoint.com/personal/vahab_crescent_com" $SharingSettings = "Disabled" # Disabled, ExistingExternalUserSharingOnly, ExternalUserSharingOnly, ExternalUserAndGuestSharing #Connect to Admin Center Connect-SPOService -Url $AdminCenterURL #Set External Sharing settings for an OneDrive site Set-SPOSite -Identity $OneDriveSiteURL -SharingCapability $SharingSettings
