Unable to open file. The file is corrupted

If you get this message “Unable to open file. The file is corrupted” when you try and open an Excel file you have downloaded from a website or received in an email try the following steps.

In this example I am using Excel 2016 but this will also work in 2007, 2010 & 2013.

1. Open Excel.
2. Click on File > Options.
3. Select Trust Center > Trust center settings.

4. Select Protected view.
5. Uncheck all the options under Protected View > Click OK.
