Missing outlook (Score 1)

I cut over to Linux recently. I loved it. The only issue I had was that there wasn't an outlook alternative. For email, Thunderbird was sufficient (I wouldn't say it was better). I used Lightning for my calendaring. This was my major problem. Things would randomly disappear from my calendar causing me to miss meetings. I had to go back to windows unfortunately. The day that there is a better alternative, is the day that I put Linux back onto my work computer.
