Office 365 ProPlus version out of support implications

Hi andykn, my apologies for the slow response.

To guarantee connectivity to Office 365 services, you'll need to be on a supported version of Office 365. That said, after September 8, 2020, Microsoft can't guarantee connectivity to Office 365 services on version 1902. This article below outlines information regarding Office 365 services connectivity, and I've also just spoken with our technical writer about updating it to provide more clarity.

Thanks so much!
