As Microsoft notes, “ we are quickly approaching the November 1 deadline…” Time can move slowly when replacing old client versions in IT infrastructures and Outlook is no different. Outlook’s November 1 DeadlineĪll of which brings me to the news that November 1 is the drop-dead date for connectivity for some older Outlook versions.

This task is harder than it seems because announcements are spread across the message center in the Microsoft 365 admin center, blog posts issued by individual development groups, plus some corporate news posts.
