I had a similar situation with an old set of Outlook messages. Manual importing was taking too much time, so I used GainTools Cloud Importer to move the MSG files directly to the IMAP account. The useful part was that I could add multiple files, choose the cloud mailbox, and select the folder where the imported emails should go. The tool supports MSG as an input and IMAP as the destination.
