I've read several post on this forum where users have saved their OneDrive folder inside their dropbox folder. My first impression would be that this could call some synchronization issues. I replied to a few of these posts and one user said they have had no issues with this, the other one said that they did have data loss. Have you tried this? Has it been reliable for you? Do you think that putting one synchronization folder inside the other would cause problems? Thank you.
