Microsoft is battling trend for frazzled office workers to give up on Outlook and switch to Gmail: it is promising 2GB+ mailboxes in Exchange 2007 rather than the piffling 50MB mailboxes most workplaces have now.
Speaking at the launch of Vista, Office and Exchange in Singapore, Microsoft Product Marketing Manager Martha DeAmicis said it had built clustered replication into Exchange so corporate IT admins wouldn"t be worrying about backing up big mailboxes to tape.
However its killer feature appears to be its plans to make those gigs of mail available on Joe Officeworker"s mobile phone.
