📌 Understanding SharePoint Permissions

SharePoint permissions can be applied at multiple levels to help you control who can view or edit files:

Permission Level	Scope	Description
Site Level	Entire SharePoint site	Controls access to all content on a site.
Library or Folder Level	Specific document library or folder	Restricts access to a single library or section.
File Level	Individual file	Grants or limits access to a specific document.

✅ You can assign unique permissions for different users or groups at each level to maintain proper security boundaries.

3. Click Stop Sharing to revoke all access.

✅ The file becomes private and is only visible to its owner.

📌 Step 4: Set Expiring Links for Extra Security

For files shared externally, use expiring links to automatically remove access after a set time.

How to Set an Expiring Link

1. Click Share on the file.
2. Choose People you specify can edit.
3. Select Set expiration date and choose your preferred date.
4. Click Apply > Send.

✅ Once the link expires, external users will no longer be able to open the file.

📌 Step 5: Control Who Can Share Files

How to Disable External Sharing (Admin)

1. Go to the SharePoint Admin Center.
2. Navigate to Policies > Sharing.
3. Adjust settings to restrict or disable external sharing.
4. Click Save.

✅ This helps maintain data security and compliance for your organization.

💡 Axio Networks Pro Tip

Combine SharePoint permissions with Microsoft 365 Sensitivity Labels to automatically apply access rules such as Confidential, Internal, or Public.
This prevents sensitive data from being shared accidentally and ensures compliance with company security policies.
