Not receiving Emails

Question

I have not received an email for three weeks now. I have looked at everything that I am comfortable with and still nothing.

Answer 1

Good day @Kim King, and I appreciate the clear explanation of your concern.  

This type of issue usually falls into one of two areas. Either emails are being delivered to your mailbox but not appearing in Outlook on your computer, or emails are not reaching your mailbox at all due to mail flow, filtering, or Exchange Online service factors related to business or school accounts. 

Please see the following workarounds that will help you verify the issue:  

Since you haven’t specified your account type (work/school vs. personal) and I’m not sure which troubleshooting steps you’ve already attempted, I may not be able to provide an exact solution yet.  

I’ll assume you’re using a work account, please try the steps below and skip any you’ve already completed.  

If you’re using a personal account or experiencing issues with both sending and receiving emails, please let me know and I’ll tailor the guidance for that scenario.  

Check Outlook on the web:

Open a web browser, then go to the browser settings and clear browsing data. Set the time range to "All time" to avoid issues caused by outdated cache.     

Go to https://www.office.com and sign in your work account.    

Once signed in, select Apps > Choose Outlook and then check whether new emails are present. 

• Scenario 1: If you can see new emails here 

This means your mailbox is receiving messages correctly. The issue is likely related to Classic Outlook on your PC, such as syncing, rules, or local settings. 

1/ Check if Outlook is working offline 

Open Classic Outlook on your computer > Go to the Send/Receive tab > Look for the Work Offline button. 

If it is enabled, click it once to turn it off. 

Make sure Outlook shows as connected after this step. 

2/ Verify Send and Receive settings 

In Classic Outlook, go to Send/Receive > Select Send/Receive Groups > Click Define Send/Receive Groups or press Ctrl + Alt + S. 

Ensure automatic send and receive is enabled and scheduled at a regular interval. 

Misconfigured settings here can delay or stop email syncing. 

3/ Check Inbox rules 

Go to File > Select Manage Rules and Alerts > Review all rules carefully. 

Look for rules that move, redirect, or delete emails. 

Temporarily disable them to test. 

Some rules may move emails out of your Inbox without being noticeable. 

4/ Check Junk Email and blocked senders 

Open your Junk Email folder > Look for any missing emails there > Review your blocked senders list. 

Note: For work and school accounts, some spam filtering is controlled at the server level. Changes made in Outlook may not always apply fully. In such cases, admin-level review may be required. 

• Scenario 2: If you do not see any new emails 

This suggests a mailbox or mail flow issue, which may involve filtering, quarantine, or a service-related problem. If you’re using a work account, please contact your IT administrator to verify the status of your mailbox in Exchange Online. In case you do not know who is your IT admin, kindly refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support  

You can share this information with them so they can check for you: 

1/ Run Message trace (Exchange admin center) 

The admin can use Message trace to check whether emails were delivered, delayed, blocked by filtering, or routed elsewhere. This helps pinpoint the exact point of failure.  

Go to Exchange admin center > Mail Flow > Message trace.  

Set Date range close to when emails were expected.  

Add sender (if known) and the affected recipient Run the trace then open Details.

2/ Check quarantine (Defender portal) 

Go to Microsoft Defender portal > Navigate to Quarantine policies.  

Verify whether the user is receiving quarantine notifications. 

If you find legitimate emails in quarantine: 

• Release them (or allow users to request release, depending on policy settings). 
• Update the quarantine policy if needed so users or admins are notified properly and can take action. 

3/ Run Microsoft 365 “Troubleshoot Email Delivery” diagnostic 

Microsoft provides an automated diagnostic specifically for email delivery: 

Launch Diag: Troubleshoot Email Delivery from the admin center. 

Enter sender, recipient and relevant info then run tests; apply the recommended fixes. 

4/ Contact Microsoft Support 

If the issue continues after these steps, the best next step is to raise a support request with Microsoft via the Microsoft 365 Admin Center > Support > Help & Support for further investigation.  

As a moderator, I don't have the tools to investigate your specific account directly because this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas. However, I will try my best to guide you as clearly as possible.     

I hope this information is helpful. If you have any questions or need further support, please don’t hesitate to reach out at any time.  

Thank you for your patience and understanding.
