Microsoft will officially end support for certain versions of Office. The news comes from Microsoft's senior product marketing manager Mariana Prudencio, who made the announcement via a Blog post. Below, you'll find the versions of Office that are affected. Everyone at Microsoft has a link to its support page, so be sure to check it out.

Microsoft will no longer support the following versions of Office.

• Office 2016 (introduced in September 2015), Office 2019 (introduced in September 2018): access 2016, Access to 2019, Excel 2016, Excel 2019, OneNote 2016, Outlook 2016, Outlook 2019, PowerPoint 2016, PowerPoint 2019, Project 2016, Project 2019, Publisher 2016, Publisher 2019, Skype for Business 2016, Skype for Business 2019, Visio 2016, Visio 2019, Kalam 2016, Word 2019

So, when is the cut off date?

Support will end on October 14, 2025.

What does this mean for me?

After October 14, 2025, Microsoft will no longer provide security fixes, bug fixes, or technical support. If you continue to use these versions after the deadline, you are exposing yourself to security risks, so please be careful. In other words, there will be no monthly Microsoft Patch Day for Office 2016 and Office 2019.

How do I proceed?

Now, you don't have to worry about switching to a new version of Office. That said, you should not use Office 2016 or Office 2019 when the expiration date has passed, at least not on computers that are connected to the Internet.

Microsoft Office Long Term Servicing Channel

Microsoft also offers Office Long Term Servicing Channel (LTSC). It allows you to use Office LTSC 2021 By 13 October 2026. The company has developed this version for devices that cannot accept feature updates or connect to the Internet.
