Understanding the Protected View

What is Protected View? 🤔

Protected View is a security feature in Microsoft Excel that opens documents in a read-only mode, primarily designed to prevent any potential risks from malware or files received from untrusted sources. This means that while you're protected from harmful content, you might also face limitations when trying to edit or fully utilize your Excel files.

There are several scenarios where you might encounter the "Excel Cannot Open In Protected View" error:

1. File Origin: Files downloaded from the internet or received as email attachments might trigger the Protected View.
2. File Location: Opening files from locations deemed unsafe, like the desktop or specific folders, can lead to this issue.
3. Corrupted Files: Sometimes, the error may arise due to a corrupted file.
4. Security Settings: Your Excel security settings might be set to high, preventing files from opening.

Troubleshooting Steps to Fix the Error
