I just recently purchased a new Mac Computer, a labtop and an iphone. In the past I have always used Entourage for my mail system. However, I really wanted to change to Apple Mail. I have heard that there are some problems using Apple Mail when sending attachments to PC users and such. I would really love my computers and iphone to all work together with my email and ical. I assume this will not be possible if I continue to use Entourage or the new 2011 Outlook. Does anyone have any sugguestions or thoughts on this?
