Question details

The user is unable to reverse their recent edits because the Undo button is unresponsive and grayed out.

Product: OneNote
Device & OS: Mac
Scenario: Trying to reverse recent changes or recover deleted text while editing a notebook page.
Observed behavior: The Undo button is grayed out and clicking it or using the undo keyboard shortcut fails to reverse the most recent actions.

Before you start

Ensure that you have actually made edits during the current active session, as the Undo button naturally grays out if the application was recently restarted or if there are no stored actions to reverse.
