I have iOS devices, but not a Mac (have a PC, with Outlook desktop client). Likely to get a mac in the future. How do I migrate my gmail (email) to iCloud and move all messages now, without the Mac Mail app? Can I somehow download my Gmail messages to Outlook and then import them to iCloud Mail? I have already exported my Gmail messages in the MBOX format, but don't know how to get them into the iCloud acount...or into Outlook, for that matter.
