We’ll be providing more information by January about how to get security updates for Office 365 ProPlus on devices running Windows 7 after support for Windows 7 ends. Make sure to discuss this process with your local IT staff before making changes to your system. When you check which version of Outlook you have, you'll. We recommend that organizations migrate to Windows 10 or a supported operating system before the end of support date on Januin order to continue receiving new feature updates to Office 365 ProPlus. Depending on the version of Outlook you have, you can find the current version number under the File menu, or by opening the 'About' menu. To find the version number of Outlook for iOS on your iPhone: In Outlook on your iPhone, select Settings > Help & Feedback. But, during that time, as long as the device is still running Windows 7, Office 365 ProPlus won’t receive any new features updates. Through January 2023, Microsoft will provide security updates for Office 365 ProPlus on Windows 7. If your organization is using Office 365 ProPlus on devices running Windows 7, we strongly recommend your organization move those devices to Windows 10.Įven though Windows 7 will no longer be supported after January 2020, we understand Office 365 customers may need more time in their migration to a supported operating system. Using Office 365 ProPlus on older, unsupported operating systems may cause performance and reliability issues over time. This includes using Office 365 ProPlus on a Windows operating system that is currently in support. Because Office 365 is governed by the Modern Lifecycle Policy, customers are required to stay current as per the servicing and system requirements for the product or service. And yes, this includes Outlook 2010 (I know there are still clients out there running Office 2010). As announced previously, Windows 7 will be out of support after January 14, 2020. In short, all clients older than Outlook 2013 SP1 with the latest fixes are no longer able to connect to Exchange Online.
