Read receipts in Outlook let you know when someone opens your email, but the person you're emailing sees a notification that you've requested this
A read receipt is a message Outlook sends back to you when the person you emailed opens it. You request read receipts on a per-email basis — you can't turn them on for all your mail at once. When you send an email with a read receipt request, Outlook will show you a notification when that person opens the message, and they'll see a pop-up asking whether to let you know they've read it.
The catch: read receipts only work if the other person's email system supports them and they choose to send one back. Many people decline the notification, some email providers strip them out entirely, and some corporate systems block them. So a missing read receipt doesn't mean someone hasn't read your email — it usually just means they didn't send one back.
Key Takeaways
- Read receipts are turned on per email in Outlook, not as a blanket setting for all your messages.
- When you request a read receipt, the recipient sees a notification asking if they want to confirm they've read your email.
- Read receipts only work if the recipient's email system supports them and they choose to send confirmation back.
- Outlook will notify you when a read receipt arrives, but you can also check your Sent folder to see which emails have been opened.
How to request a read receipt on a single email in Outlook desktop
Open Outlook and start composing a new email or reply. Type your message and add recipients as normal. Before you send, look for the Options tab in the ribbon at the top of the compose window (in newer versions of Outlook, this may be labeled as a three-dot menu or gear icon depending on your version).
Click Options, then look for a button or checkbox labeled Request a Read Receipt or Request Read Receipt. Click it to turn it on — you'll usually see a small icon appear in the compose area to confirm it's active. Then send your email normally. When the recipient opens it, Outlook will send you a notification.
If you can't find the Options tab, your version of Outlook may have moved this feature. In Outlook 2016 and earlier, the read receipt option is under the File menu at the top left — click File, then Properties, and check the box for Request a Read Receipt.
How to request a read receipt in Outlook on the web
Log into your Outlook account at outlook.office.com and click New Message to start an email. Type your message and add recipients. Look for the three-dot menu icon (usually in the bottom left or top right of the compose box, depending on your screen size) and click it.
Select Request a read receipt from the dropdown menu. You'll see a confirmation that it's turned on. Send your email, and you'll receive a notification when the recipient opens it.
What happens when someone receives your read receipt request
When the recipient opens your email, a dialog box pops up on their screen asking: "The sender of this message has requested a read receipt. Do you want to send a read receipt to [your name]?" They can click Yes to send you confirmation, No to decline, or sometimes Never send a read receipt to this sender to block future requests from you.
Many people click No out of habit or privacy preference. Some corporate email systems are set up to decline read receipts automatically. Email providers like Gmail don't support read receipts at all, so if you send one to a Gmail address, the recipient won't see the notification and you won't get a confirmation.
How to check which emails have been read
Go to your Sent folder in Outlook. Look at the column headers — you should see a column labeled Icon or Flag Status. If an email has a small icon (often a checkmark, envelope, or read receipt symbol) next to it, that means a read receipt was received. Hover over the icon to see the date and time the email was opened.
In Outlook on the web, open your Sent folder and click on an email you sent with a read receipt request. In the message details pane on the right, you'll see a section showing whether a read receipt was received and when.
Why someone might not send you a read receipt
The most common reason is that they simply clicked No when the notification appeared. Some people view read receipts as intrusive and decline them as a matter of privacy. Others may not notice the notification at all, especially if they're checking email on a phone or tablet where the dialog might appear differently.
Corporate email systems often block read receipts entirely for security or policy reasons. If you're emailing someone at a large company, their IT department may have disabled the feature. Email services like Gmail, Yahoo Mail, and some others don't support read receipts at all — the feature simply won't work with those addresses, and you won't know whether the email was opened.
When read receipts are actually useful
Read receipts work best for time-sensitive internal emails within an organization where everyone uses Outlook and has read receipts enabled. They're helpful if you're sending something urgent to a colleague and need to know whether they've seen it before following up.
For external emails, especially to clients or people outside your organization, read receipts are unreliable enough that you shouldn't depend on them. If you need to know whether someone has received and read something important, it's better to ask them directly or request a reply confirming they've seen it.
Frequently Asked Questions
Can I turn on read receipts for all my emails at once?
No, Outlook doesn't have a global setting to request read receipts on every email you send. You have to turn it on individually for each message before you send it. Some email management tools can automate this, but the standard Outlook interface requires you to enable it per email.
What if I send a read receipt request to a Gmail address?
Gmail doesn't support read receipts, so the recipient won't see a notification asking whether to confirm they've read it. You won't receive any confirmation, even if they do open the email. The feature simply doesn't work between Outlook and Gmail.
Can someone tell if I declined their read receipt request?
Yes, they'll see that no read receipt was received. However, they won't know whether you declined it, your email system doesn't support it, or you simply haven't opened the email yet. From their end, it just looks like no confirmation came back.
Do read receipts work on mobile Outlook?
Requesting read receipts on mobile Outlook is more difficult — the feature isn't always visible in the mobile app's compose interface. It's easier to request them through Outlook on the web or the desktop version. If someone sends you a read receipt request on mobile, you'll still see the notification asking whether to confirm.
Is there a way to block read receipt requests from specific people?
When you receive a read receipt notification, you can click Never send a read receipt to this sender to block future requests from that person. Outlook will then automatically decline any read receipt requests from them going forward.
