Outlook for Microsoft 365 Apps Feature Update for March 2024

Microsoft has released the March 2024 feature update of Outlook for Microsoft 365 Apps in the Current Channel.

There is no new feature for Outlook, but OneNote contains a Preview of the New Sticky Notes app. These notes are stored within your Outlook mailbox (Exchange Online or Outlook.com) but gives you a much better “small-note” taking experience than within Outlook itself.
