Microsoft retiring older versions of Office 2013 and 2016

Microsoft are updating the supported versions of Outlook for Windows that can connect to Microsoft 365 services.


Starting 1 November 2021, and due to be complete by mid-May 2022, 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
Office 2013 15.0.4970.9999 and older
Office 2016 16.0.4599.9999 and older
Microsoft 365 Apps for enterprise (formerly Office 365 ProPlus) 1705 and older
Microsoft 365 Apps for business (formerly Office 365 Business) 1705 and older


Supported versions of Outlook will continue to connect to Microsoft 365 services as expected.

We recommend that all users regularly update to the supported versions of Office and Microsoft 365 Apps.  If you are subscribed to the Workstation Management service, this is completed automatically providing you are Office 2013 or above.

In the meantime if you have any questions please contact your Account Manager, or if you are not a customer of Connect Systems please get in touch and we’ll be happy to help.
