    Hello Sue,

    Thank you for providing the additional context regarding the POP account configuration. Because POP accounts download and store messages locally on the Mac rather than continuously synchronizing folders with the server, missing emails in specific folders typically indicate a local display filter issue, or a partial data migration if the application was recently updated to the "New Outlook" interface.

    Please perform the following troubleshooting steps to locate and restore the missing emails.

    Step 1: Check Current Views and Filters

    Sometimes filters can hide messages and make folders appear empty.

    1. Open one of the empty folders.
    2. Click the Filter icon in the top-right of the message list and select Clear All if available. Make sure no filters (Unread, Flagged, Has Attachments) are applied.
    3. Set Sort By to Date and scroll through to check for older messages.

    Step 2: Revert to Legacy Outlook

    The "New Outlook for Mac" manages local POP data and "On My Computer" folders differently than previous versions. If the application was recently switched to the New Outlook interface, the existing local folders may not have migrated completely. Switching back temporarily will confirm if the data is still safely stored on the hard drive.

    1. Open Outlook and select the Help menu at the top of your Mac screen.
    2. Choose Revert to Legacy Outlook and confirm the prompt to restart.
    3. Check the affected folders.

    Step 3: Re-Import Local Data (If applicable)

    If the emails are successfully located within Legacy Outlook, the data is safe. To use the New Outlook interface moving forward, the local data must be manually migrated.

    1. Switch back to the New Outlook using the toggle in the top-right or via the Outlook menu.
    2. Go to File > Import and choose Local data or On My Computer data.
    3. Follow the on-screen prompts to migrate your saved POP emails.

    Please let me know if these steps help or if you’re still experiencing the issue. I’d be glad to continue assisting further.

    Check these areas to restore or view the emails in the folders in Outlook for Mac:

    1. Confirm Outlook is online and connected
    • On the Outlook menu, ensure Work Offline is not selected.
    • Go to Tools > Accounts.
    • In the left pane, select the mail account and check the status icon:
      • If the icon is orange or shows an error, there is a connection problem. Fix connectivity (network, credentials, server) and, if possible, sign in to the same mailbox via Outlook on the web to confirm the emails still exist on the server.
    1. If the account is Exchange, rebuild the folder cache If the folders exist but appear empty, the local cache may be corrupted. Rebuilding the cache forces Outlook to download all items again from the Exchange server.

    Caution: Emptying the cache removes any data that exists only locally and is not synchronized with the server (for example, unsynced items or certificates). Ensure important data is on the server or backed up before proceeding.

    For each folder that shows as empty:

    1. Make sure the Mac is connected to the Exchange server (no connection error in Tools > Accounts).
    2. In the folder list, Ctrl+click or right‑click the Exchange folder that appears empty.
    3. Select Properties.
    4. On the General tab, choose Empty Cache.
    5. Wait while Outlook automatically re-downloads the items from the Exchange server into that folder.

    Repeat for other affected folders if needed.

    1. If items still do not appear
    • Recheck that Work Offline is not enabled.
    • Verify the Exchange account shows as connected (no orange indicator) in Tools > Accounts.
    • If Outlook connects but the server mailbox itself has no items in those folders, recovery would need to be done from server-side backup or restore options managed by the mail provider or administrator.

    If the account is IMAP/POP and the folders are empty both in Outlook and in the provider’s webmail, the messages are no longer present on the server and would similarly require restore from backup if available.
