I’ve recently encountered a issue with Google Domain Apps Premium where buy a large amount of users on my Google apps account have left the business. I now want to re-use their accounts but need to backup/Archive their emails. The only solutions I have found are:

An IMAP account in outlook exported to a PST files or Backupify.com.

Now considering IMAP/Outlook takes an age to download and then create a PST file, Backupify seems to be the only option I can find. I’m now going to use the free trial of that to try one account. However if anyone else has any (free!) options please do let me know!
