When opening (Excel) reports from FBO One in Excel 2010 you may see the following warning:
Excel is trying to warn you this file came from an 'unsafe' location (the internet) and forces you to press the button before editing the file. This warning can be disabled in Excel by going to:
File -> Options,
Then select 'Trust Center' and click the button 'Trust Center Settings'
There, uncheck the top two checkboxes, to disable the protected view for files from the internet and files located in potentially unsafe locations.
Then click OK to save the settings and close the trust center window, and then OK again to close the Excel options.
Now the 'Protected View' mode will be disabled for all Excel report downloaded from FBO One (and the internet).
