You can password protect Word and Excel documents you create on a desktop PC. Unfortunately, Word and Excel Mobile on the Pocket PC cannot handle password protection set by the desktop PC version of the programs. If you e-mail or copy a password protected document to your Windows Mobile device, you will not be able to open it on the Pocket PC. If you are sending a document to a Pocket PC, first remove password protection from the documents on your PC. To set and remove password protection on the PC,
follow these steps: Word documents: Open the document in Word on your PC, click on File > Save As > Tools > Security Options. From this screen you can set or delete the password. Excel documents: Open the document in Excel on your PC, click on File > Save As > Tools > General Options. From this screen you can set or delete the password.
