Product: Microsoft Office
Device & OS: not provided
Scenario: Attempting to open or edit a password-protected Office document without knowing the password.
Observed behavior: The file prompts for a password and blocks access or editing until the correct password is provided.

Before you start

Before attempting to recover or bypass a password, gather any previous versions of the file or backups you might have saved. Also, try recalling common passwords you frequently use, as encryption is designed to be highly secure.

Solution 1Recommended

Handling a Forgotten 'Password to Open'

What to do when you cannot open an encrypted file.

Microsoft Office uses strong encryption for files secured with a 'Password to Open'. Because of this security design, there is no built-in or officially supported way to recover or bypass a forgotten open password.

Check for backups

Look for earlier, unencrypted versions of the file in your backup drives, cloud storage (like OneDrive or Google Drive), or email attachments.

Test common passwords

Test any standard passwords or variations you might have used when originally securing the document.
