Observed behavior

Solution 1Recommended

Manually Apply the Required Sensitivity Label

Since Office web apps do not currently support applying automatic sensitivity labels post-editing like desktop apps, you must manually apply the label to unlock editing features.

When an organization requires mandatory labels for files stored in SharePoint or OneDrive, the web app enforces this rule before allowing any changes. Applying a label satisfies the policy.

1
Open the document

Open the affected document in your preferred Office web app, such as Word Online, Excel Online, or PowerPoint Online.

2
Locate the Sensitivity menu

On the Home tab of the top ribbon, look for the 'Sensitivity' button, which often features a padlock or shield icon.

3
Select a label

Click the Sensitivity button to open the drop-down menu of available labels configured by your organization. Click on the appropriate label (e.g., General, Confidential) based on your document's content.

4
Resume editing

Once the label is applied, the restriction prompt will disappear, and you can resume editing the document normally.

Frequently Asked Questions

Why do I get this prompt in the web app but not the desktop app?

Desktop Office applications support more advanced auto-labeling policies that can evaluate content during or after editing. Office web apps currently require the label to be applied upfront before editing begins when a mandatory policy is enforced on SharePoint or OneDrive.

Can I bypass the 'Add Sensitivity Label' requirement?

No. If your IT administrator has configured a mandatory sensitivity labeling policy for the SharePoint site or OneDrive folder, you must apply a valid label from the provided list to unlock editing capabilities.

What if the sensitivity label options are missing or grayed out?

This usually happens if your account does not have the correct Microsoft 365 license for Information Protection, or if your browser session has timed out. Try signing out and signing back in, or contact your IT department to verify your label permissions.

Will my desktop apps start requiring labels before editing too?

While desktop apps usually evaluate labels dynamically, organizations can update their Microsoft Purview policies to enforce stricter mandatory labeling across all platforms, which may eventually cause desktop apps to exhibit the same pre-editing block as web apps.
