I use this service to keep my business up-to date with all of our clients that are using Office 365! It makes things easy by allowing me access from anywhere, anytime with no need for an internet connection or anything like it.
When you're working remotely one thing is always needed - your network drive/sync folder so everything syncs just fine without any issues at all. Great customer support too if something should go wrong in between services (which has never happened). We have multiple offices around the world which means we can't easily meet every time someone needs help but they still benefit because their files stay updated even when not meeting.
