Find Missing Outlook Notes: 6 Ways to Recover

If your Outlook notes have disappeared, you can usually recover them by checking the Notes folder, rebuilding the search index, restoring from a backup, or using the Recoverable Items folder in Exchange or Microsoft 365. This guide covers the most common causes and the step-by-step fixes that work for Outlook 2016, 2019, 2021, and Microsoft 365.

Why Do Outlook Notes Go Missing?

Outlook notes are stored as items in your mailbox, not as separate files. They can vanish for several reasons:

• Accidental deletion – You or a sync client moved them to Deleted Items.
• Search index corruption – The notes exist but don’t appear in search results.
• Sync errors – A conflict between your local cache and the server caused items to disappear.
• Corrupted Outlook data file (.ost or .pst) – The file that stores your local copy of notes got damaged.
• Recoverable Items retention – In Exchange or Microsoft 365, deleted items are held for a limited time (usually 14 days, but admins can change it).

Knowing the cause helps you choose the right recovery method.

Method 1: Check the Notes Folder and Deleted Items

Before doing anything technical, verify that your notes aren’t simply hidden or in the trash.

1. In the left navigation pane, click the Notes icon (or press Ctrl+5). If you don’t see it, go to View > Folder Pane and make sure “Normal” is selected.
2. If your notes are not there, go to your Deleted Items folder (or Trash in Outlook on the web). Look for items with a note icon.
3. If you find them, right-click and choose Move > Other Folder, then select Notes.

If you don’t see the Notes folder at all, it might be hidden. In the folder pane, click the … (more) button and select Notes.

Method 2: Rebuild the Search Index

Often notes are still there, but Outlook’s search can’t find them because the index is stale or corrupted. Rebuilding the index forces Outlook to re-scan your mailbox.

1. Close Outlook.
2. Open Control Panel and go to Indexing Options (type “indexing” in the Start menu).
3. Click Advanced (you may need admin rights), then under “Troubleshooting,” click Rebuild.
4. Wait for the rebuild to complete (can take an hour or more). Then reopen Outlook and search for your notes.

If you’re using Microsoft 365, you can also try Search Tools > Search Tools in Outlook’s search tab and select “Indexing Status” to see if indexing is complete.

Method 3: Use Recoverable Items (Exchange / Microsoft 365)

If you deleted notes permanently (Shift+Delete) or they disappeared after a sync, they may still be in the Recoverable Items folder on the server. This works for Exchange, Microsoft 365, and Outlook.com accounts.

1. In Outlook, go to your Deleted Items folder.
2. Click the Recover items recently removed from this folder link at the top (or go to Home > Recover Deleted Items).
3. Select the notes you want and click Restore Selected Items.

This only works if the items are still within the retention period (usually 14 days, but your admin can extend it). If the link is grayed out, your organization hasn’t enabled it.

Method 4: Repair Your Outlook Data File

If your notes are missing and you’re using a POP or IMAP account with a .pst file, the file may be corrupted. Outlook has a built-in repair tool.

1. Close Outlook.
2. Go to Control Panel > Mail (or search “Mail” in the Start menu).
3. Click Data Files, select your account, and click Open File Location to find the .pst file.
4. Run SCANPST.EXE (usually in C:\Program Files\Microsoft Office\root\Office16).
5. Follow the prompts to repair the file, then reopen Outlook.

For Microsoft 365 accounts, the local cache is an .ost file that Outlook can rebuild automatically. If you suspect corruption, you can delete the .ost file (but first make sure you have a good internet connection – Outlook will re-download everything from the server).

Method 5: Restore from a Backup

If you have a backup of your Outlook data (e.g., a .pst backup, or a system image), you can restore the notes from there. This is most useful if the notes were on an old computer or a previous profile.

• PST backup: If you have a .pst file from before the notes disappeared, you can import it via File > Open & Export > Import/Export and choose “Import from another program or file.”
• Windows File History: If you have File History enabled, you can restore the .pst file from a previous version.
• Cloud backup: Some third-party backup tools back up Outlook data; check their restore options.

If you don’t have a backup, you may still be able to recover notes from the Recoverable Items folder (Method 3) or from a previous version of your mailbox if your admin has enabled litigation hold.

Method 6: Check for Hidden Notes or a Different Account

Sometimes notes are not missing – they’re just in a different place than you expect.

• Multiple accounts: If you have more than one email account in Outlook, notes are stored per account. Check the Notes folder under each account.
• Hidden folders: In the folder pane, click the … icon and select Folder List to see all folders, including hidden ones.
• Search all items: In the search box, type kind:note (or note) and press Enter. This searches all folders, not just the current one.

If you still can’t find them, try opening Outlook in safe mode (Win+R, type outlook.exe /safe) – this disables add-ins that might interfere.

Frequently Asked Questions

Can I recover permanently deleted notes after 30 days?

It depends on your mailbox’s retention policy. In Microsoft 365, deleted items are typically kept for 14 days, but admins can extend it up to 30 days. After that, they’re gone unless your organization has litigation hold or eDiscovery enabled. If you’re on a personal POP/IMAP account, permanent deletion is usually final.

Why did my notes disappear after updating Outlook?

Updates rarely delete notes, but they can cause a sync issue or corrupt the search index. Try rebuilding the index (Method 2) or restarting Outlook. If that doesn’t work, check if your account is still connected properly (File > Account Settings).

Do notes sync across devices?

Yes, if you’re using an Exchange, Microsoft 365, or Outlook.com account, notes sync to all devices. If you’re using POP or IMAP, notes are stored locally on each device and don’t sync.

Can I recover notes from a .pst file that I deleted?

If you deleted the .pst file itself, you might be able to recover it with file recovery software, but that’s not guaranteed. If you have a backup (like File History), restore it first. Otherwise, try the Recoverable Items method if the notes were in an Exchange account.

What if I don’t see the Notes icon in the navigation pane?

Right-click the navigation bar (the bottom of the left pane) and choose Navigation Options. Check the box next to Notes. You can also press Ctrl+5 to jump directly to Notes.

Are there any third-party tools that can recover Outlook notes?

Yes, several data recovery tools claim to recover Outlook items from .pst/.ost files. However, they are not official Microsoft tools and can be expensive. Try the built-in methods first – they cover most cases.
