I got my yahoo mail and exchange email to setup fine. However, my gmail account after I set it up just has a red triangle next to it, and I have no idea how to fix it. Please help. ;(
Make sure when you add your Gmail account that you (allow eM Client access) to your Gmail account near the end of the automatic Gmail Wizard setup. See this thread below.
