Microsoft made two changes to Office Mobile applications. New features and changes do not get tested against these older versions of Office, and this may lead to unexpected issues according to Microsoft.īoth Office versions reach end of support on October 14, 2025. Microsoft explains that some functionality and features may not become available, and that users may 'encounter other unexpected performance or reliability issues while using Microsoft 365 services'. Connections may continue to work, but there is no guarantee for that. The same applies to Office 20 on October 10, 2023. Microsoft notes on this support page that older Office versions 'might still be able to connect to Microsoft 365 services, but that connectivity isn't supported'.

Microsoft explains on a support website that only mainstream support versions of Office are supported for connecting to Microsoft 365 services.
