Decent but Lacking
The email client is okay, but lacking in features and sometimes response time. The most horrible part Ive had experience to date is calendaring, what a nightmare. Im currently working in one timezone, the account was created with PST. When I create calendar appointments, Im using the current time in my timezone. When I save the app, it readjusts the time to PST? What the hell, there isnt even a mention of timezone when scheduling. If I modify the time on the event again, it works. Horrible, must be using server side for creating appointments, put the timezone in the add event form/screen...
