Read receipts in Outlook let you know when someone opens your email, but the person receiving it has to allow it
A read receipt is a notification that comes back to you when the person you emailed opens your message. In Outlook, you can request one on individual emails or set your account to request them on everything you send. The catch: the recipient's email settings control whether you actually get the notification. If their Outlook is set to never send read receipts, you won't hear back even if they read the message.
This matters because read receipts are not the same as delivery confirmation. Outlook can tell you an email reached someone's mailbox (that's a delivery receipt). A read receipt means they actually opened it and looked at it. Neither one tells you if they understood it, agreed with it, or will act on it — just that the message arrived and was viewed.
Key Takeaways
- Request a read receipt on a single email by opening the message, clicking Options, then checking "Request a Read Receipt" before you send.
- Set Outlook to request read receipts on all outgoing mail through File > Options > Mail > Tracking, then check "Request a read receipt for all messages I send".
- The recipient can decline to send a read receipt, and many people set their Outlook to never send them, so you may not get a response even if they read the email.
- Read receipts work best within organizations where everyone uses the same email system; they often fail or don't work at all when emailing outside your company or to different email providers.
Request a read receipt on one email before you send it
The fastest way is to ask for a read receipt on just that one message. Open a new email in Outlook, write your message, and before you click Send, look for the Options tab at the top of the compose window. Click it, then look for "Request a Read Receipt" in the ribbon. Check that box, then send the email as normal.
If you don't see an Options tab, you may be using Outlook on the web instead of the desktop version. In Outlook on the web, click the three dots (more options) at the bottom of the compose area, then look for "Request a read receipt" in the dropdown menu. Check it and send.
Set read receipts for all your outgoing emails
If you want Outlook to ask for a read receipt on every email you send, go to File in the top left, then click Options. In the left sidebar, click Mail. Scroll down until you see a section called "Tracking" — this is where Outlook keeps all the read receipt settings.
In the Tracking section, check the box next to "Request a read receipt for all messages I send". You can also check "Request a delivery receipt for all messages I send" if you want to know when emails arrive, separate from when they're opened. Click OK at the bottom to save your changes. From now on, every email you send will include a read receipt request.
What happens when someone receives your read receipt request
When you send an email with a read receipt request, the recipient sees a notification asking whether they want to send you a read receipt. In Outlook desktop, they usually see a bar at the top of the email asking "The sender of this message has requested a read receipt. Send a read receipt?" They can click Yes or No.
Many people click No, and some set their Outlook to automatically decline all read receipt requests without asking. This is why you might never get a read receipt even though you know the person read your email. There's no way to force someone to send you one — it's entirely their choice.
Read receipts often don't work across different email systems
Read receipts work most reliably when both people use Outlook within the same organization. If you email someone at a different company, or if they use Gmail, Yahoo, or another email provider, the read receipt request usually doesn't work. Their email system may not support it, or it may strip out the request before it reaches them.
Even within the same organization, read receipts can fail if someone forwards your email, opens it on a phone instead of a computer, or uses a mail client that doesn't support them. The bottom line: treat a read receipt as a helpful signal when it works, but don't rely on it as proof that someone read your message.
Turn off read receipts if you don't want to send them
If you receive emails with read receipt requests and don't want to send them back, you can set Outlook to decline automatically. Go to File > Options > Mail > Tracking. Look for "Responses" and choose one of the options: "Always send a read receipt", "Never send a read receipt", or "Ask me before sending a read receipt".
Choosing "Never send a read receipt" means Outlook will automatically decline every request without bothering you. This is common in workplaces where people get dozens of emails a day and don't want the extra notifications. Your choice here doesn't affect whether you can request read receipts from others — it only controls what you send back when someone asks for one.
When read receipts are actually useful
Read receipts work best for time-sensitive messages within your own organization. If you send a meeting reminder to your team and want to know who opened it before the meeting starts, a read receipt can help. If you're sending a document that needs approval and want to confirm the decision-maker saw it, a read receipt gives you that confirmation.
They're less useful for routine emails, external communication, or anything where you need proof of understanding rather than just proof of viewing. If you need to know that someone actually read and understood your message, follow up with a phone call or ask them to reply. A read receipt only tells you the email was opened, not what the person did with the information.
Frequently Asked Questions
Can I see if someone declined my read receipt request?
No. Outlook doesn't tell you whether someone clicked No or simply ignored the prompt. You only get a notification if they click Yes and send the read receipt back. If you don't hear anything, you can't tell whether they declined, never saw the request, or their email system doesn't support it.
What's the difference between a read receipt and a delivery receipt?
A delivery receipt confirms the email reached the recipient's mailbox. A read receipt confirms they opened the message. You can request both separately. Delivery receipts are more reliable because they don't depend on the recipient's choice — the email system sends them automatically.
Do read receipts work on mobile Outlook?
Read receipts work differently on Outlook mobile apps. You can request them when composing an email, but the recipient may not see the same notification they would on desktop. Some mobile email apps don't support read receipts at all, so the request may not go through.
If I set read receipts for all emails, will people get annoyed?
Some people find constant read receipt requests annoying, especially in high-volume email environments. It's more common to request them only on important messages. If you work in a place where everyone uses Outlook and read receipts are normal, it's usually fine to request them on everything.
Can I take back a read receipt request after I send the email?
No. Once you send an email with a read receipt request, you can't change it. If you realize you didn't need one, you can send a follow-up email without the request, but the original message will still ask for a read receipt if the recipient hasn't opened it yet.
