My company “upgraded” my laptop from Windows 7 to 10. My MS Outlook 2016 is behaving very strange. First, subfolders of the inbox won’t appear until I create a “test” folder in the inbox. Then I have to do this for each subfolder. I also noticed an intermittent problem with attaching files from the toolbar (nothing happens), and my signature doesn't appear in a new email, even when I try to insert it from the toolbar (nothing happens). These problems all disappear when I run Outlook in Safe Mode, and the subfolders all appear in OWA. Our IT department thought they fixed it, but the problems reappear intermittently depending on what I do.



What I have tried so far:

* Uninstall Office and reinstall
* Remove email profile and create a new one
* Run command > outlook.exe / resetnavpane
* Run command > outlook.exe / cleanviews

Thanks in advance for any ideas or suggestions.
