emails from a safe sender are being put into junk......how do I fix this?

If emails from a safe sender are being incorrectly classified as junk, you can try the following steps to resolve the issue:

1. Check Junk Email Options: Go to the Home tab in Outlook, click on Junk, and then select Junk E-mail Options. Ensure that the sender's email address is listed in the Safe Senders tab.
2. Review Safe Senders List: If the email address is already in the Safe Senders list, try removing it and then re-adding it. This can sometimes refresh the settings.
3. Disable the "Also trust e-mail from my Contacts" Option: If this option is enabled, Outlook may be adding all your contacts to the Safe Senders list, which could exceed the limit and cause issues. You can find this option in the Safe Senders tab of the Junk E-mail Options.
4. Check for Filters or Rules: Ensure that there are no additional rules or filters set up in Outlook that might be moving emails to the Junk folder.
5. Update Outlook: Make sure that your Outlook application is up to date, as updates can fix bugs related to junk email filtering.
6. Use MFCMAPI: If the issue persists, consider using the MFCMAPI tool to check for any misconfigurations in the junk email settings. This tool can help you manage and troubleshoot your mailbox settings more deeply.

If these steps do not resolve the issue, you may need to look into the configuration of your Exchange server settings or consult with your IT department for further assistance.

Hi @B T,  

Welcome to the Microsoft Q&A forum.   

Thank you for contacting us regarding emails from a Safe Sender being delivered to your Junk folder. We truly appreciate you bringing this to our attention and apologize for the inconvenience.  
Even if the sender is on your Safe Sender list, emails can still be routed to Junk due to strict organization-level anti-spam policies, missing domain authentication (SPF/DKIM/DMARC), or conflicting Outlook rules and filters. 

The Q&A Assist response accurately covers key troubleshooting steps, such as checking Junk Email settings, refreshing Safe Senders, adjusting rules, updating Outlook, and using MFCMAPI for advanced fixes.

I’d like to provide some additional information, which I hope will be helpful to you:  

1/ Verify organization anti-spam policies (Microsoft 365) 

If your organization uses Microsoft 365, please contact your IT team to perform the following steps: 

Step 1 - Access Microsoft 365 Defender 

• Navigate to the Microsoft 365 Defender portal. 
• Sign in using your admin account credentials. 
• Go to Email & collaboration → Policies & rules → Threat policies. 
• 
• Select Tenant Allow/Block Lists. 

Step 2 - Unblock a sender 

If legitimate emails are being blocked: 

• In Tenant Allow/Block Lists, select the Domains & addresses tab. 
• Locate the blocked email address or domain. 
• Select it and click Remove to delete the block entry. 
• Confirm and save your changes. 

Step 3 - Allow a sender 

To ensure emails from a trusted sender are always delivered: 

• In Tenant Allow/Block Lists, go to the Domains & addresses tab. 
• Click + Allow to create a new allowed entry. 
• Enter the sender’s email address or domain. 
• (Optional) Set an expiration date for the allowed entry. 
• Click Save to apply the changes.

2/ Confirm sender domain authentication 

• If emails are still flagged as suspicious, the sender’s domain may lack proper SPF/DKIM/DMARC configuration. 
• You can ask the sender to verify and set up these records to ensure email authentication. 

3/ Mark email as “Not Junk” 

• Open the Junk Email folder. 
• Select the misclassified email. 
• Click Move to Inbox (or Move → Inbox). 
• 

After moving, Outlook will learn this behavior and reduce the chances of misclassification in the future 

4/ Contact Microsoft Support   

If the issue persists even after these steps, it may stem from a deeper system-level cause. In this case, I recommend contacting your organization's IT administrator, who can submit a support request to Microsoft through the Microsoft 365 Admin Center. They’ll be able to access system-level information to investigate the issue thoroughly and provide assistance. At the very least, they can offer the most effective workaround to ensure your experience remains smooth and secure.
