Microsoft gets in its way of its own success here. Like always, Microsoft tries to force you to use their cloudstorage, nearly blocking and ignoring Google drive and others. Here’s a novel idea, Microsoft: Put your customer’s interest #1. If Google or Apple are helping your customers store files, be happy for them, because they are helping your customers succeed and you LOVE your customers. Now connect your services to these platforms, so that your customers have the best experience using your powerpoint app. Lovely! If your cloud storage has a major benefit to us. Seduce us. No is no though. Respect and support your customers choice for other cloud services.
