Hidden Emails

It sounds like the emails you received may be hidden due to a filtering issue in Outlook. Sometimes, emails can become hidden if a filter is applied to the default view settings of your Outlook folder. To resolve this, you can try the following steps:

1. In the ribbon, select the View tab.
2. In the Current View area, select View Settings.
3. Select Filter, and then review the tabs for any selections that could filter out specific messages, such as date received, keywords, or read/unread status.

Additionally, if the emails are not appearing in Cached mode, you might want to clear the offline items in your Inbox to resynchronize them:

1. Right-click the Inbox folder and select Properties.
2. In the Inbox Properties dialog box, select the General tab.
3. Select Clear Offline Items and confirm the action.
4. Press Shift+F9 to force the resynchronization of your Inbox folder.

These steps should help you regain access to the hidden emails.

Hi @Barragan, Andrew

Thank you for posting your question in the Q&A Forum. 

I understand how frustrating it can be when important emails are hidden or become inaccessible. Based on your description, here are some steps you can follow to resolve this issue in Outlook for Mac: 

Initial Checks and Verification 

Before performing any major resets, please follow these quick steps to verify and address any minor issues: 

• Verify Emails on Webmail: Access your email account through a web browser (Outlook Web Access/OWA) to confirm the missing emails are visible and fully synced on the server. This ensures your data is safe. 
• Check Filters: Ensure that no display filters (such as showing only Unread or emails flagged as Important) are currently applied to your Inbox view. Filters can sometimes hide emails unintentionally. 
• Check the 'Other' Tab: If you are using the Focused Inbox feature, make sure to check the Other tab at the top of your mailbox list. The email may have been automatically sorted there. 
• Verify Archive and Deleted Items: Double-check your Archive and Deleted Items (or Trash) folders to ensure the emails have not been accidentally moved there. 

Clear the Cache by Resetting the Account 

If the issue persists, clearing Outlook's cache can help resolve synchronization problems, as a corrupted cache can sometimes cause emails to disappear or become hidden. Here’s how to reset your account: 

• Open Outlook and go to Tools > Accounts. 
• In the left pane, select the account that is having issues. 
• At the bottom left, click the three dots and select Reset Account. 

This will force Outlook to re-sync the data from the server. Please note that this will delete any unsynchronized data, so ensure your emails are synced to the server before proceeding.

Re-Configuration and Updates 

• Ensure Your Outlook is Up to Date: To make sure your application is running the latest version and has all the necessary bug fixes, go to Help > Check for Updates. 
• Re-Configure Your Email Account: If the issue persists, try removing and re-adding your email account to reset the settings and force a fresh sync: 
• Go to Tools > Accounts. 
• Select the problematic account and click the minus (-) button to remove it. 
• Add the account again by clicking the plus (+) button. 

Please let me know if any of these steps help resolve the issue, or if you need further assistance. I’m happy to guide you through the process.
