Protect the Workbook and Isolate the Affected Excel Feature

Quick Excel Check

First, create a support ticket through the Microsoft 365 Admin Center by selecting Help & Support. Next, use the Office JavaScript API for Office Add‑ins and design around its documented limitations (for example, workbook switching and coauthoring behavior), and verify the final state before changing any backup or secondary account.
