About this tag
The new Outlook tag on WindowsForum.com covers Microsoft's ongoing transition from Outlook Classic to the web-based new Outlook for Windows. Recent discussions highlight feature rollouts tracked through the Microsoft 365 Roadmap, including a searchable Go to Folder command via Ctrl+Y, conditional formatting for message lists, and offline attachment support. Performance comparisons show notification delays improved to about five seconds, still behind Classic. Enterprise timelines shifted, with the opt-out phase now beginning March 2027. Other updates include Planner integration, PST import for GCC and worldwide tenants, and a focus on reducing context switching. The tag is useful for IT professionals and users tracking new Outlook's evolution and its impact on productivity workflows.
