OneNote for Mac lets you recover single pages or entire sections of notes that you have recently deleted. While viewing recently deleted notes, you can restore their pages or sections by moving them back to their original notebook or to another location you want.
OneNote keeps deleted notes for a period of 60 days, after which they are permanently erased.
View recently deleted notes
In any notebook, do the following:
On the View tab, click the small arrow next to the Deleted Notes button, and then click View Deleted Notes.
In the Deleted Notes view, click the tab of the deleted page or section that you want to look at.
When done, exit this view by clicking Exit ( X ) to the right of the Deleted Notes section label.
Note: Pages and sections that have been deleted do not appear in the results list of a notebook search. To include such notes in a search, you must first restore them.
Restore recently deleted notes
While viewing any page or section in the Deleted Notes view, do the following:
Control-click the tab of the page or section that you want to restore.
On the menu that appears, click Restore To.
Select the destination where you want to move the deleted notes, and then click Restore.
Note: When you restore a single page of notes from the Deleted Notes view, it is moved to the section in the notebook you choose. If you restore an entire section, it will be moved to the notebook you choose, along with all of the previously deleted pages in that section.
Permanently delete recently deleted notes
OneNote keeps deleted notes for a period of 60 days, after which they are permanently erased. You can do this manually at any time (for example, to remove confidential information from the deleted notes in a shared notebook) by doing the following:
In the Deleted Notes view, Control-click the tab of the page or section that you want to permanently delete.
On the menu that appears, click Delete permanently.
Tip: As a safeguard, OneNote offers one more chance at recovery immediately after you do this. If you change your mind, press Command-Z on your keyboard to return the erased note to the Deleted Notes view, or click Undo Delete on the Edit menu.
