Designed to replace the current Mail and Calendar apps, the new Outlook can only be removed after it's been installed.

For several months now, Microsoft has been urging Windows users to switch over to the new Outlook app, with classic Outlook recently getting an official “death date”. Many aren’t happy about this, holding off on jumping ship as long as they can — but the clock is ticking down.

Microsoft will force install the new Outlook email client on Windows 10 systems starting with next month's security update.

The good news is that the February update which brings the new Outlook doesn't strip out the old version of the app, so you can still use that.

Microsoft will automatically install its new Outlook client on Windows 10 PCs with next month’s Patch Tuesday update.
