Hi IBN
Thanks for reaching out to Microsoft Q&A forum support
Based on your description, I understand that when you attempt to reply to an email, your own email address automatically populates the "To" field, causing the message to either send to yourself or reappear in your inbox. Even after manually replacing your address with the intended recipient, the issue persists, leading to confusion about whether the email was successfully sent.
This issue typically arises due to how email clients handle reply to logic, especially when the original message was sent only to you or involved a distribution group that includes your address. Some email systems may default to your own address in replies if no other recipient is detected, or if auto-BCC rules are configured. Additionally, certain threading behaviors or encryption settings (like S/MIME) can cause the email to appear as if it was sent to yourself, even when it was not.
To address this issue, consider the following approach:
- Check Your Reply Settings
- In Outlook, go to File > Options > Mail > Replies and Forwards.
- Ensure that “Always BCC myself” or similar options are disabled.
- Review Rules and Alerts
- Navigate to File > Manage Rules & Alerts.
- Look for any rules that automatically CC or BCC your own address and disable them.
- Expand Distribution Groups
- If replying to a group, click the + next to the group name to expand it.
- Manually remove your own address before sending.
- Use “Reply All” Carefully
- Sometimes using “Reply All” instead of “Reply” can help ensure the correct recipients are included.
- But always double-check the “To” and “CC” fields before sending
