We recently upgraded from Office Suite 2007 and Windows 7 to Office Suite 2016 and Windows 10. We are running into an issue with Outlook email attachments all being read-only so the user cannot modified the attached Excel or Word document re-save and mail back to the originator. Our research shows this is by default/design with the newer Office products. Is there a way to change that default so attached files are editable by default. We also noticed also that non-office attachments (3rd party applications) are also read only when they have never been before.
We have hundreds of users and we are hoping there is something we can "push" by group policy.
