Hi all-- First, thanks for the wealth of information on this forum--I have lurked quite a bit the past several days and learned a lot. Here is my situation. I am finally upgrading from a 2007 white Macbook to a refurbished 2012 Macbook Air which I should receive in the next couple of days, and I want to move all of my old e-mails from Entourage 2004 onto the new computer. I rely on Word & Excel so I know I'm going to have to buy MS Office 2011, since I have read that 2004 (the version I own) doesn't work on Mountain Lion. My question is--should I buy Outlook or use Apple's Mail? Or is there another option that is even better? From what I understand Mail works better with the Mac OS, which makes sense. But I do want to make sure that (1) I can pull in and keep old e-mail folders & their content from Entourage into whatever client I use, and (2) when others read the e-mails I send, formatting is clean. I am a writer and when submitting work I usually have to copy/paste sample pages into the body of the e-mail, and I want to minimize strange line breaks/weird characters when my e-mails are read so that I don't get a rejection simply because something didn't translate well across e-mail systems. So which would best suit my needs--Outlook or Mail? Alternatively, I do use Gmail at work and wouldn't be completely opposed to switching over to that if it works better, though it does mean I'll have to let all my contacts know I've changed my primary e-mail address, which is a bit of a pain. Also, what is the best way to transfer my old e-mails into the new client? I've read that I need to pull the individual folders onto the desktop to create mbox files--then simply save them onto an external drive and pull them into Apple Mail? Any advice or links to resources here would be appreciated. Thanks in advance for the help.
