Some Windows 10 users are starting to see a Focused Inbox feature show up in the Mail app.

After revealing its plans in September to bring Focused Inbox to its Outlook Mail app on Windows 10, Microsoft is finally preparing to introduce that feature to Windows 10 devices from next month.

Microsoft is adding new customization options to Virtual Desktops and changing things around for several inbox apps (including Notepad) in its Windows 10 Dev Channel test build 21337.

Focused Inbox for Outlook is a familiar feature to Android and iOS users, but it has yet to arrive for those on Windows 10 PCs and Mobile. Microsoft has now announced that it has started rolling out.

Windows 10 Mail users should see Focused Inbox over the coming weeks, as well as a host of updates to Calendar.
