Just a suggestion maybe a folder that allowed everyone access that could have subfolders might be a great way to help your clients seeing as we are all working remotely for the foreseeable future.

The My Company folder allows some access but not full access to all levels of access and has no ability to organize files.

This would allow your clients to use your product instead of a Dropbox or Google account. It would keep files safe and allow managers, AE's, and assistants to share files like research and proposals.
