Orange Email Closing

Does anyone in the tech side know how to get emails from a wanadoo account in Office 2007 into a gmail one? The "Easy to Follow" guide is as much use as the proverbial chocolate fireguard. I have imported the contacts over, and that took two days of messing about, but I cannot get the emails in folders I named Holidays and Car Insurance where I keep pdf's of documents. I have tried forwarding from the folders but they bounce back as too large. I cannot copy and paste them either, so I am at a loss. Any ideas guys?

Once I setup Import mail and contacts in Gmail, I had to move my orange emails from the folder to the inbox, and then they moved to my gmail automatically. I also had to create a new folder in gmail and move the imported mails from orange to the folder I created. hope that helps

Thanks Punkin, I'll give that a go.
