- Microsoft has not specified a release date for the new Outlook Mac but a few things are clear. First, it will be the best Outlook yet, perhaps on any platform, in terms of appearance and design. This is not a high bar: Outlook on Windows is a mess from a user interface perspective, and has dialogues buried within that have not changed for decades.
- Like Microsoft Entourage for Mac 2008, Outlook 2016 for Mac and Outlook for Mac 2011 are intended to be purely locally cached mail clients. Changing the location or using a mail identity that is located on an external hard disk or a network is not supported.
