What if your plans change and you no longer need an Outlook note? Fortunately, notes don't have to stick around forever. You can write one this morning and throw it out this afternoon. What could be easier?
To delete a note, following these steps:
Click the Notes button in the Navigation pane.
Your list of notes appears.
Click the title of the note you want to delete.
Click the Delete button on the Ribbon (or simply press Delete).
Poof! Your note is gone forever. Even if you were making plans for your next bestseller in that note, you won't be able to get them back.
