Go to the 'Share' tab on the ribbon, and choose 'Notebook Recycle Bin' in the 'History' group. If you have deleted within the past 60 days will appear in this area, you can restore them by right-clicking any page and choosing 'Move or Copy...'. Choose where you would like to place the page, click the 'Move' button. That is for One Note 2010-13 (sometimes it works in the previous versions also). IF it is 2007 then you should be able to File --> Open Backup and then get the pages back if you have backed them up.
Sorry I will not be able to call. I can opt out for another expert to see if they can call you if that is what you wish?
Hi there and welcome
It is easier then calling if I connect to your computer and do this for you to see if this is recoverable.
Is this possible? If so, please accept the request and I can do this.
Thank you Joyce.
