MC1041465 - New Microsoft Outlook for Windows and Outlook on the web: Optimized hover actions in the message list
Message Center
What changed since this version
Updated April 28,October 16, 2025: We have updated the timeline below. Thank you for your patience.
In new Outlook for Windows and Outlook on the web, the hover actions in the message list will be moved to the Sender/From column to be more space-efficient and minimize unnecessary mouse travel for users with their Reading Pane set to Hide or Bottom. The large width occupied by the DateTime Received column will thus be reduced. For all users, a one-time shortcut to change/set your hover actions will be provided. After the changes to the hover actions, the first action will be replaced by a quick button (gear button) to change/set your hover actions. After that button has been triggered once, it will disappear, and your hover action settings will kick in fully.
This message is associated with Microsoft 365 Roadmap ID 429868.
When this will happen:
