I have a user where when he receives a warning message for any email with pdf attachment he receives. The only way to get rid of it is to run outlook in admin mode and unchecking the box. Unfortunately, the popup shows up again after few weeks. He is also the only person experiencing this. My question is how can I disable this popup message permanently?
Things I have tried
- Removed/disabled all adobe Foxit addons from outlook
- Reinstalled office and made sure it's up to date. He has E3 license and used the online installer for installation.
