Not able to see all my emails

It sounds like the issue you're experiencing with not being able to see all your emails in your inbox may be related to filtering settings or synchronization problems in Outlook. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check Filtering Options: Sometimes, items may not appear because a filter is applied to the view settings. To check this:
   • In the ribbon, select the View tab.
   • In the Current View area, select View Settings.
   • Select Filter and review the tabs for any selections that could be filtering out specific messages, such as date received, keywords, or read/unread status.
2. Clear Offline Items: If you're using Cached Exchange Mode, you might want to clear the offline items in your Inbox to force a resynchronization:
   • Right-click the Inbox folder and select Properties.
   • In the Inbox Properties dialog box, select the General tab.
   • Click Clear Offline Items, then confirm the action.
   • Press Shift+F9 to force the resynchronization of your Inbox folder.
3. Run Outlook with the /cleanips Switch: This command can help resolve issues with items not appearing in your Inbox:
   • Exit Outlook.
   • Start Outlook using the command line with the following command: Outlook.exe /cleanips.
4. Check for Updates: Ensure that your Outlook application is up to date, as updates can fix known issues.

If these steps do not resolve the issue, consider checking your mailbox settings or contacting your IT support for further assistance.

Hi @Akshay Goel, 

Thank you for reaching out to the Microsoft Q&A forum.  

Based on your description, you’re unable to see all emails in your Inbox in Classic Outlook, while searching by sender shows those messages as Unread. We truly understand and appreciate the effort you’ve already taken, including resetting the view and starting Outlook in Safe Mode. 

This behavior usually occurs when Focused Inbox or a filter hides items from the current view, when conversations are collapsed or sorting obscures newer mail, or when rules move messages to other folders. It can also be linked to search indexing and sync settings, which may show items in search that aren’t currently displayed in the message list. The steps below are tailored to address these common causes and should suit your situation. 

Below are a few options that may address your needs effectively: 

1/ Firstly, proceed by running a Message Trace to check message flow. 

• Please involve your tenant admin to run a message trace in the Exchange Admin Center (EAC). This will help determine whether the email was ever received by EOP and provide visibility into its delivery status. Run a message trace and view the results in the Exchange admin center in Exchange Online | Microsof…   
• If the trace shows no record of the email, it confirms that the message did not reach Exchange and may have been blocked or failed at the connector level.   

2/ Then, stop mail-moving rules and confirm that syncing is working correctly. 

• File > Manage Rules & Alerts, temporarily uncheck rules that move or delete messages.

• File > Account Settings > Account Settings > select your account > Change > enable Use Cached Exchange Mode, then restart Outlook. 

• If your account is IMAP: right‑click Inbox > IMAP Folders… > Query and Subscribe to folders that should appear. 

3/ Afterward, troubleshoot search issues and repair the data file as needed. 

• Rebuild the index: close Outlook, open Control Panel > Indexing Options > Advanced > Rebuild, then reopen Outlook and allow time for indexing. 

• Repair the data file: close Outlook, run scanpst.exe (Inbox Repair Tool), select your OST or PST, start the repair, then reopen Outlook. 
• For your information: Troubleshooting Outlook search issues - Microsoft Support 

4/ Lastly, consider advanced recovery options should the problem persist. 

• Create a new Outlook profile: Control Panel → Mail → Show Profiles → Add; set up the account again and make the new profile default. 
• Repair Office installation: Control Panel → Programs and Features → Microsoft Office → Change → choose Quick Repair or Online Repair. 

• Disable non‑essential add‑ins: File → Options → Add‑ins → Manage COM Add‑ins → Go… → uncheck all non‑essential add‑ins. 

• Run Microsoft Support and Recovery Assistant (SaRA): download from aka.ms/SaRA-OutlookSetup and follow the prompts to automatically diagnose and fix Outlook issues. 

5/ As your account is managed by your organization, please contact your IT administrator to check your permission and policies. For a more efficient resolution, we recommend using your administrator account or contacting your IT administrator to submit a support request directly to Microsoft Support team.
