Getting two copies of a Sent Email in my Sent folder on Outlook using my Yahoo POP email account

Dear Dennis DeAndre,  

Thank you for reaching out to the Microsoft Q&A Community. I understand you're experiencing a frustrating issue where two copies of every sent email are appearing in your Sent folder. This is a problem with POP email accounts and can be easily corrected.  

When you use a POP account with Outlook, the duplicate emails are typically caused by a double-saving process. One copy is saved locally by Outlook for Mac as soon as you hit "send." A second copy is then saved by your Yahoo server. Because your POP account is configured to download all messages from the server, Outlook then downloads the server's copy of the sent email, resulting in two identical copies in your Sent folder. The "autogenerated" email address on one of the copies is often a result of how the server formats the email headers for its own record.  

Please kindly follow this step   

Step-by-Step Guide to Resolve the Duplicate Emails  

Step 1: Access Account Settings  

1. Open New Outlook for Mac.  

Click on the "Outlook" menu in the top-left corner of your screen.  

Select "Settings" and then choose "Accounts".  

In the accounts window, select your Yahoo POP email account.  

Step 2: Disable Saving Sent Emails  

In your account settings, click on the "Advanced" tab.  

Under the "Folders" section, you should see an option for "Sent" or "Sent Items."  

Look for a checkbox that says something like "Save sent messages in the Sent folder." This is the key setting.  

Uncheck this box. By doing this, you are telling Outlook not to create its own copy. The server will still save a copy, and Outlook will download that one, ensuring only a single copy appears in your folder.  

Step 3: Restart Outlook  

Close and then reopen Outlook for Mac to ensure the new settings have been applied.  

Send a test email to yourself or a colleague to confirm that only a single copy now appears in your Sent folder.  

I hope these steps help you resolve the problem. If you require additional guidance, feel free to reply to this thread and I’ll be happy to assist you.  

Warm Regards,
