Where to find read receipts in Outlook
Read receipts in Outlook work differently depending on which version you use. In Outlook on the web (the browser version), go to Settings (the gear icon in the top right), select "View all Outlook settings," then navigate to Mail > Message handling. Check the box next to "Request a read receipt for messages I send." In Outlook desktop (Windows or Mac), the setting lives in File > Options > Mail > Tracking, where you'll find "Request a read receipt for all messages I send."
Once you turn on read receipts globally, Outlook will ask the recipient's mail server to send you a notification when they open your message. Not every recipient will have read receipts enabled on their end, so you won't always get a response — but when you do, you'll see it in your Inbox as a separate message.
If you only want read receipts for specific messages rather than all of them, you can skip the global setting and instead request a receipt on a per-message basis. In Outlook on the web, open a new message, select the three dots menu, and check "Request a read receipt." In Outlook desktop, click the "Request Read Receipt" button in the Message tab of the ribbon.
Key Takeaways
- In Outlook on the web, enable read receipts through Settings > View all Outlook settings > Mail > Message handling.
- In Outlook desktop, go to File > Options > Mail > Tracking and check the box for requesting read receipts on all messages.
- You can request a read receipt for individual messages without turning on the global setting by using the per-message option.
- Read receipts only work if the recipient's email system supports them and has not disabled them on their end.
What happens when someone opens your message
When a recipient opens an email you've sent with a read receipt request, their mail server generates a notification and sends it back to you. This notification arrives as a separate message in your Inbox, usually with a subject line like "Read: [Original message subject]." The timestamp on the read receipt shows when the recipient opened the message, not when they sent it.
Some recipients will see a prompt asking whether they want to send you a read receipt. If they click "No" or dismiss the prompt, you won't receive one — and you'll have no way of knowing whether they declined or simply never opened the message. This is why read receipts are not a reliable way to confirm someone has actually read and understood your email.
Why read receipts might not work
Many email systems and clients don't support read receipts, or users disable them for privacy reasons. Gmail, for example, does not have a built-in read receipt feature, so if you send a message to a Gmail address with a read receipt request, you won't get one back. Outlook users can turn off read receipts in their settings, and some organizations disable them across their entire mail system.
Even when both sender and recipient have read receipts enabled, the feature depends on the recipient's mail server actually processing the request. Some corporate firewalls or mail filters strip out read receipt requests before they reach the user. If you're not receiving read receipts from certain people or domains, it's usually because their system doesn't support them rather than because they're ignoring your request.
Read receipts versus delivery confirmation
Read receipts and delivery confirmation are two different things. Delivery confirmation tells you that your message reached the recipient's mail server — it arrived in their mailbox. Read receipts tell you that the recipient opened the message. You can have delivery confirmation without read receipts, and you can request read receipts without knowing whether the message was delivered.
In Outlook, delivery confirmation is usually on by default. You'll see a notification in your Sent folder or as a separate message when mail is delivered. If you need to know whether someone received your message but don't care when they open it, delivery confirmation is what you're looking for. If you need to know they've actually read it, you need read receipts — but remember that many recipients won't send them back.
Privacy and etiquette considerations
Requesting read receipts on every message can feel intrusive to recipients, especially in casual or external communication. Some people view read receipt requests as a sign of distrust, and many disable the feature specifically to avoid sending them. In a professional setting with colleagues who expect it, read receipts are usually fine. In external communication or with people who don't know you well, use them sparingly.
If you're using read receipts to track whether someone has seen an important message, consider sending a follow-up message instead if you don't hear back within a reasonable timeframe. That approach is more direct and doesn't rely on a feature that many people have disabled. For truly urgent matters, a phone call or instant message is more reliable than waiting for a read receipt.
Turning off read receipts
If you've turned on read receipts and want to disable them, the process is the same as turning them on. In Outlook on the web, go back to Settings > View all Outlook settings > Mail > Message handling and uncheck the box. In Outlook desktop, go to File > Options > Mail > Tracking and uncheck the box for requesting read receipts.
You can also prevent others from seeing that you've read their messages by disabling read receipt responses. In Outlook on the web, this is in the same Message handling section — look for an option about responding to read receipt requests. In Outlook desktop, it's in the same Tracking menu. Disabling responses means you won't send read receipts to others, even if they request them.
Frequently Asked Questions
Can I see read receipts for messages I sent in the past?
No. Read receipts only work on messages sent after you turn on the feature. If you enable read receipts today, you won't retroactively receive receipts for emails you sent last week. You can request a read receipt on a new message, but the recipient would need to open that new message for you to get the notification.
What if someone opens my email multiple times?
You'll typically receive only one read receipt per message, even if the recipient opens it several times. The read receipt is generated the first time they open it, and most mail systems don't send additional notifications for subsequent opens. Some mail clients may behave differently, but a single receipt is the standard.
Do read receipts work with forwarded or replied-to messages?
No. A read receipt applies only to the original message you sent. If someone forwards your email to another person, that forwarded copy is a new message, and your original read receipt request doesn't follow it. If someone replies to your message, the reply is a separate email and doesn't trigger your original read receipt.
Can I request a read receipt on a message I've already sent?
No. You can only request a read receipt when you're composing and sending a new message. Once a message is in your Sent folder, you cannot add a read receipt request to it. If you need a read receipt for something you already sent, you'll have to send a new message asking the recipient to confirm they received and read the original.
