So I recently updated from 10.14 to 10.15, and everything looks good except for MS Word. I keep my Dropbox file on an external drive (formatted as Mac OS Extended Journaled), and whenever I try to edit and save a Word document to the Dropbox location, I get a dialog box with "Check to make sure the removable drive containing this file is still available." It then renames the file to a temporary file name (e.g. .~WRD1234) and then brings up the File Save As dialog box.
The whole thing repeats if I try to give it a new name.
I've reindexed my Dropbox folder, removed the MS word cache, etc. etc. I'm on client build v212.4.5767.
I did not see this behaviour with previous versions of Mac OS, so I'm assuming something broke with the update.
Anyone with any ideas?
