If you are using a multi-lingual enabled computer, make sure that the language that was used to create the password is enabled when you enter the password. Before entering a password, verify that the CAPS LOCK keyboard option is not turned on. If you forget or lose the password, you cannot open the document. A password-protected document can only be opened if the correct password is supplied.

Passwords prevent unauthorized access to documents. This error can appear if you try to open a password-protected Word document and you do not provide the correct password. Clicking the ' Show Help' button on the 'wrong password' dialog displays this expanded notice:

If someone clicks Cancel or enters the wrong password, they'll get a clear error message, and know that they need credentials to view this particular document (nothing cryptic).

You and others will get the Microsoft Word password prompt for protected documents: enter the password you chose and hit Enter:

Re-open the document through ' File > Recent' (or double-clicking it in the Open dialog or Windows Explorer).

After having saved any other edits, close that file (no need to exit Word itself).

Hit Esc to return to your document: from here, everything looks normal, and you can resume editing it as you would any other Word document.
