Focused Inbox, the AI-powered feature that can surface your most important emails appears to be rolling out to some Windows 10 Mobile users in the Release Preview Ring. The news comes from a report from German website WindowsUnited.de, which showed it working in the following screenshot (via Windows Central).
The Focused Inbox is already live on the desktop version of the Windows 10 app, and you can turn it on by going into Settings > Reading. We’re not seeing it on our Release Preview Windows phones as of yet, so Microsoft could well be doing some A/B testing (as it did with the Photos app recently). Focused Inbox can be really useful if you receive a lot of emails, and it will be a great addition to the already solid Outlook Mobile app on Windows 10 Mobile handsets.
