Constant database conflicts
One should never use DropBox, OneDrive, or similar locations for the back end accdb of an Access relational database application. It's surprising, in fact, that it ever really worked for your organization. My guess is that users were not trying to work with it simultaneously before. Or perhaps they were actually using the version in the network folder, not in Dropbox.
That's the only safe way to do it.
If you must allow remote access, and that's a lot more common today, then you'll need to find a suitable method of sharing the data in the back end.
One option is migrating data to an environment which CAN support multiple users, such as SharePoint lists or a SQL Server database, hosted or remote.
Another option is to user remote desktops to have users connect to an inhouse copy of their Accdb FE on a computer inside your network.
