The steps above apply to Excel 2016, Word 2016, PowerPoint 2016, Excel 2013, Word 2013, PowerPoint 2013, Excel 2010, Word 2010, and PowerPoint 2010. Microsoft Access 2010, 2013, and 2016 is the same steps but you need to open the database exclusively first. In the video below I open an Access database in exclusive mode at 00:59.
Chris Menard tip
When I encrypt a file with a password, I usually save the file in a folder or drive that only I can access or only people that should access to that file. Ideally, don’t put your encrypted files in a drive or folder that everyone can access.
