I like that it's easy enough anyone can use this without any training or knowledge of other programs needed! It also gives you so many options when creating your own events/meetings as well if there are multiple people attending (such scheduling).
There isn't much but sometimes having more than one person using something at once makes things difficult - especially in regards to updating databases while others work from their computers simultaneously. Also would be nice just have some sort of calendar where all users could see what was going down during certain times instead being restricted by time zones only seeing updates after they've left thoughout out office hours? Having such great tools available really helps us keep up our organization even through holidays we don’t get paid vacations off anymore!!
