I love how it syncs with my outlook calendar so that if someone comes in late or misses an appointment they are notified immediately! This is very helpful when we have multiple people working from home because sometimes one person will forget something at work but not realize until after leaving their house hours later (or even days). Sometimes there isn't much room left before hitting send which could be improved upon; however this rarely happens unless several emails were sent back-to -back within minutes/seconds time frame without any space between them meaning more than likely all had been checked off by previous emailers already -.-.
