I have 3Gb mails on Gmail. I used Microsoft Outlook 2007 for imap.

But the PST file is only 400MB. Isn't that supposed to be 3GB

Email clients typically have settings that you can configure to keep attachments on the server until requested, download only headers until a message is being read, etc. You likely don't have Outlook set up to download the full contents of your mailbox right off the bat.

IMAP is intended to be a remote protocol. By default it leaves messages on the server and manages them there. There's options in Outlook to enable "offline" storage of email.
