Was using Dropbox for Outlook (Add in) for past few months. Its the desktop version - Did all the latest updates. Just recently stopped working. Does not display anylonger either. Had removed and added back in a few times but no change. Any one else have this problem / solution. Do not really use office 365 for my email. like using the desktop. Does Dropbox need to update this add-in perhaps? Very helful for PDF Files that share with others into Dropbox folder directly. Very easy to use. Looking for a solution. Thank you!!
