According to Paul Thurott, award winning technology journalist and blogger, Microsoft has revealed ” that it will support the classic version of Outlook for Windows through at least 2029, which should placate those commercial customers who are concerned about the lackluster quality of the new Outlook. That said, the new Outlook will soon reach general availability (GA), and when that milestone occurs, it will replace the classic app in new Microsoft 365 installs”.
“ ‘Currently, the new Outlook for Windows is available for preview for commercial customers and is getting closer to readiness for General Availability,” Microsoft’s Margie Clinton writes in the announcement post. ‘“The migration will be a multi-year journey delivering more capabilities in new Outlook, working with customers assessing feedback and readiness, and providing admin guides and tools to ensure customers have what they need to prepare accordingly.’ ”
