I do not have a paid Box account, but the other party has a paid Box subscription. On the other hand, I have a paid subscription to Microsoft365 and the other party does not.

So I was hoping to be able to sync my Sharepoint folder with their Box folder, but I don't know how to do that. I would like to know if anyone knows how to do this.

The reason why I want to do that is that I can have them guest share their Box folder and store their files there, but that would mean that I would have to manage both Sharepoint and Box. That would be a bit of a hassle.

Thank you in advance for your help.
