How to check outlook mail receiver seen or not

In Outlook, you can check if an email has been read (or "seen") by the recipient by using the "Read Receipt" feature. Here's how:

Method 1: Request a Read Receipt

1. Compose a new email or reply to an existing one.
2. Click on the "Options" button in the "Tags" group.
3. Click on "Request Read Receipt" (or "Request a Read Receipt" in older versions of Outlook).
4. Send the email as usual.

When the recipient opens the email, they will receive a prompt asking if they want to send a read receipt. If they agree, you will receive a notification with the recipient's email address and the date and time they opened the email.

Method 2: Check the Email Header

1. Open the email you want to check.
2. Click on the "View" tab in the ribbon.
3. Click on "View Settings" (or "View" > "View Settings" in older versions of Outlook).
4. In the "View Settings" window, click on the "Other Settings" button.
5. Scroll down to the "Headers" section.
6. Check the "Received" header for the recipient's email address. If the email has been read, the "Received" header will show the date and time the email was opened.

Method 3: Use a Third-Party Add-in

There are several third-party add-ins available that can help you track email opens and reads, such as:

• Boomerang: A popular add-in that allows you to track email opens, sends reminders, and more.
• Sanebox: An email management tool that includes features like email tracking and read receipts.
• HubSpot: A marketing and sales tool that includes email tracking and analytics features.

Keep in mind that some recipients may not agree to send read receipts, and some email providers may block or disable this feature. Additionally, some email clients, like Gmail, do not support read receipts by default.
