I'm trying to migrate several folders of e-mails (containing several subfolders of e-mails) from an Exchange account into a Gmail account.

Some of the folders that I'd like to migrate, have already been moved to "On My Computer" within Outlook 2011.

I have added the Gmail account to Outlook as an IMAP account, but it's not letting me move/copy folders from either "On My Computer" or the Exchange account into the Gmail IMAP account. When I try to drag a folder from either, it doesn't let me drop them into the IMAP account.

Can you please advise how I can achieve this?

Thanks
James
