Microsoft changes New Outlook default switching deadline that was set to happen very soon

Microsoft has an important update for 365 Enterprise users. The company has shared when it will automatically switch them from Classic to New Outlook for Windows.

Back in December of 2024, Microsoft had shared a timeline for when Microsoft 365 Enterprise users would be switched over to New Outlook for Windows from the classic app. At the time, the company had said that the big switch would happen in April 2026, which means it was set to happen around one month from now.

So if you were preparing to make the jump, you can rest easy, as Microsoft has given more time. The company, last month, shared an update to this timeline and it has said that the opt-out phase for New Outlook for Windows has been pushed back to March of 2027, so admins and users alike will get a whole new year for making the switch.
