Does anyone use Microsoft Groove with their clients? I signed up for the free trial to try with my partner but it seemed to take a long time for her to download it. I don't want it to be a hassle for our clients and take up too much space on their computers but I think it would be a great program to use in order to limit the amount of emails sent and received. Also, if we invite our clients to join a workspace do they have to have Microsoft Groove too?
