Re: How to share a folder to an private person out of our company?
If that user needs to upload data do that folder then need to be a Standard user. You can click on the Manage Persmissions on that folder and then you can invite a "Standard" user with their email address. You can change the permissions on that invite section.
We have a few cleints that have people that only need to download the files in those folders, they have shared those links set to not expire and have a password... Document the link and the password for references.
