I hate the outlook calender so much but I have no choice because it's the only one authorized by my work. The Google calendar is far superior. This one is blank half the time and I have constantly open it and close it. Sometimes the account won't show up so I can't save an entry so I have to restart it. No to-do reminder option like Google has, and no monthly calendar widget like Google. Awful calendar app I waste so much time getting it to work.
