Masterpassword not being prompted

I have a spreadsheet that is saved using a masterpassword, however, LibreOffice does not prompt me for the password unfortunately when I open the spreadsheet.

Does this issue happen to you as well to an xlsx file please or am I doing something wrong?

Coming to think of it, this file has been saved on Skydrive so it “might be” that Microsoft engineering might have removed its own security features through some integretative technology.

Just to clarify this happens when I am using LibreOffice Calc.

Support for MS SharePoint and SkyDrive services is currently a Google Summer of Code idea. Exactly when support for these services will be implemented is unclear. To be clear, I am not suggesting that access to these services is your issue, but rather that the file having been on SkyDrive may (as you suggest) be part of the problem. Perhaps try testing with a file that has not passed through SkyDrive?
