Microsoft is introducing a feature in New Outlook that groups email notifications to reduce interruptions and notification fatigue. Users have reported that New Outlook is slower than Outlook Classic, with email opening times taking up to 30 seconds compared to just a few seconds in the Classic version. There are also reliability issues with notifications in New Outlook, which can be inconsistent or absent for connected accounts on Windows 10 and 11. Despite the planned improvements, Outlook Classic remains more efficient for managing notifications and opening emails quickly.
