I migrated my Thunder bird mail over to my iMac. I now have all of my e-mail worrk. I now want to figure out how how to make the font larger in the pane that is the message list. I can increase and decreaes the font so I can see it when I have selected an e-mail and opened it up but talking to the Pencil Necked Geek @ Apple Care is really trying. I went from a head of coal black hair on Thursday to being totally white headed yesterday. I do have my e-mail working now.I don't use the built in email program. We have Office 2011 on our Macs and we both use Outlook. Have you tried Thunderbird?
I just use gmail. Easy to access from everything.
Might not be ideal for everyone though.
I tried g-mail, but it wouldn't let me use my e-mail address without modifying it, :rant:
