I'm looking for an Outlook email/calendar program that operates in the cloud and will allow me export all of my current Outlook 2003 email folders, messages and calendar entries into the cloud email program. I currently use Outlook to aggregate several email accounts (comcast, gmail, school) onto my home desktop. But I want to be able to access my "home PC outlook" from anywhere. I checked out Office Live 365 but it only seems to allow cloud storage via skydrive and the Outlook program still runs on your PC. (By the way, when I installed the Office Live 30 day trial it disable my Outlook 2003...had to reinstall it to get everything back) Any ideas on a cloud application that does what I want. Thanks!!!
Gmail will allow you to "aggregate" all your accounts. You go to Settings > Accounts to setup the Gmail browser "client" to access your various email accounts. You can also set it so that when you respond to a message from another account in Gmail, it will still look like you are replying from the other account rather than from Gmail.
I am not aware of any other email service that offers the same. I don't believe Outlook.com does. I know that iCloud does not. I have no clue about Yahoo's email system.
If you have Outlook setup to access your Gmail account by way of IMAP, then you can just drag/copy any old messages/folders from other accounts in Outlook to your Gmail account in Outlook and they should then be in Gmail. You may still have some minor cleaning up to do as you need to remember that Gmail technically does not use "folders", but rather "labels".
