When I try to open an excel file being sent to by email (office 365) it says the file is corrupt and can't be opened.  I went into trust center and unchecked the protected view for attachments and now it works.  Why did I have to do this?  This just happened today and I have been using this computer and the MS office 365 account for the past 2 weeks.  It was an upgrade from win 7  pro to win 10 pro, and then I installed office 365 after upgrade.
