Outlook for Old Outlooks Is Not Good


MS Outlook 2013 Logo

Outlook 2010, 2007, and older are no longer supported by Microsoft Office 365. If you are using any of these versions or even unpatched versions of Outlook 2013, you will have trouble connecting to your Office 365 mail.


Microsoft announced earlier this year, “after November 1, 2021, only Outlook 2013 Service Pack 1 (with latest fixes) and later will be able to connect to Microsoft 365 services. It’s worth noting here that Outlook 2007, 2010, and Office 2013 versions earlier than 15.0.4971.1000 aren’t supported now, but we know some customers just can’t quit them.”


Folks who have delayed upgrading to current Outlook versions will begin to experience connectivity issues with Office 365. They can purchase one-time license upgrades or subscription-based licenses for Office 365 applications that are always the latest version.


We like the subscription option as it’s flexible and allows quickly adding and removing users as needed. Billing is monthly, so you pay for only the licenses you need. License management with a subscription is simple, and deployment of new installs is fast and dependable.


If you are using Outlook versions older than 2013, you need to upgrade now. Outlook 2016 will work until October 2023. We recommend employing Office 365 Standard licenses, which include “always up to date” versions of the Office Suite for the best performance.
