Office 365 – End of Life for Office/Outlook 2013 and 2016 on Windows
Software end of life.
It’s not something anyone really wants to think about. Especially time-strapped business owners and leaders.
But end of life is an important part of the product lifecycle. After all, a company can’t support a product forever, when new-and-improved versions are perpetually on the horizon. No new features will be added to end-of-life products, and official support will cease, allowing companies to focus on the newer offerings.
Continuing to use something that is no longer supported is risky, as vulnerabilities will no longer be patched. Sub-optimal performance and lack of compatibility are also expected consequences.
To meet performance expectations, Microsoft are updating the supported versions of Outlook for Windows that can connect to Microsoft 365 services.
Effective November 1, 2021, the following versions of Outlook for Windows, as part of Office and Microsoft 365 Apps, will not be able to connect with Office 365 and Microsoft 365 services.
|Office and Microsoft 365 Apps
|Outlook for Windows Version
|15.0.4970.9999 and older
|16.0.4599.9999 and older
|Microsoft 365 Apps for enterprise (formerly Office 365 ProPlus)
