Bleh, Microsoft’s Public Folders feature worked wonderfully on Outlook for Mac. My company recently moved to Group Mailboxes when Microsoft deprecated Public Folders. We were told that it would be possible to archive messages from an inbox to a Group Mailbox on iPhones (and Macs) just like Windows, but six months in and the feature does not exist outside Windows. Microsoft Support recommends that we request the feature and folks did 7 months ago, but there’s still no official word for if or when this feature will show up. Microsoft, please bring feature parity across platforms.
