Dear np999,
Thank you for posting in the Microsoft community.
I understand that you've encountered a situation where your Outlook notes were lost due to reconfiguration, and I'm sorry to hear that.
Under normal synchronization conditions, Outlook notes are synchronized to the server. According to your description, since you're unable to see these notes on the server-side (i.e., the web version), it indicates that they were not properly synchronized. Therefore, the only way to retrieve these notes would be to search for local backup files on your current MAC device:
- Check Outlook Data Files:
- Open Finder.
- Go to /Users/YourUsername/Library/Group Containers/UBF8T346G9.Office/Outlook/.
- Look for a folder named "Outlook Notes." Your notes may be stored here.
- Restore Backups:
- If you have Time Machine backups, you can try restoring the Outlook data file from the backup.
- Open Time Machine.
- Navigate to the date and time of the backup and locate the Outlook data file in the path mentioned above.
- Restore the file and then re-add it to your Outlook account.
If all local files fail to contain these notes, unfortunately, it's highly likely that they may no longer be recoverable. I apologize for any inconvenience this may cause. We appreciate you spend your time working on this issue. I wish you all the best.
