Microsoft 365 apps will continue to function after the Windows 10 end of support date, but there could be issues over time.

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

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

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.
