In the past week when using Outlook (Office 365) if I try and view an Email Excel attachment I get an Excel message caused I think by HP Sure Click that:

When I click on Repair Now the Excel session just terminates.
The only way round the problem is to file the attachment, right Click and select Remove protection

Is this a new feature that has been introduced if so, how do I turn it off, or get it so that it works without having to first file attachments?
