I am a heavy Outlook user on my office computer. I use Touchdown on my Android phone which is very full-featured and customizable. Since getting an iPad, I have been very disappointed in the iOS Mail and Calendar apps. They aren't as feature-rich as what I'm used to, and the Calendar app routinely screws up recurring meeting changes. I have found three possible alternatives on the App Store. I'm hoping to find some folks here who have used some of them before I pay for apps that might or might not fit the bill. Has anyone used any of the following: Exchange Mail by Naethyn Outlook Email by iKonic Outlook Mail Pro by Code Before Dawn Thank you.
