Yeah, I'll have to read up on that some more. You must be talking about 'Anyone Links' in Teams, right? The basic thing that needed to happen when Sharefile was the right solution was the ability of folks outside the company to send something to an employee securely. Sharefile integrates with Outlook, and folks can put "Click HERE to send me a secure file" links in their email signatures. So all anyone has to do is find a previous email from the employee and click on the link to start the process. Simple & bulletproof.
With Anyone Links, I think the employee has to be in charge of the interaction of sharing a file outwards, right? How does an external person send a document TO the employee that didn't originate FROM the employee with this tech?
Also, I think this requires E3 licenses, right? So they definitely are paying for it if they would have otherwise survived on a lower license - although definitely not as much as Sharefile - haha.
