Outlook Read Receipts: Does Outlook Track Your Email?

An Outlook read receipt is a request, and you are allowed to refuse it. Microsoft's own help page says so: "There is no way to force a recipient to send a read receipt." Whether a sender can even ask depends on which Outlook they use and which account sits behind it. A Microsoft 365 work mailbox can. A free Outlook.com inbox in the browser cannot. Outlook read receipts are also the visible half of the story. Tracking pixels ask nobody, and what Outlook does with them differs across classic Outlook for Windows, new Outlook, Outlook on the web, Outlook for Mac and the phone apps. We read Microsoft's documentation for each one on October 8, 2026.

Key Takeaways

• Microsoft's read receipt help page states "You can't request a read receipt in Outlook.com," and says the feature "isn't available for IMAP or POP accounts such as Gmail, Yahoo!, or iCloud."
• Exchange's ReadReceiptResponse setting accepts DoNotAutomaticallySend, AlwaysSend and NeverSend, and Microsoft documents DoNotAutomaticallySend as the default for Outlook on the web.
• Classic Outlook for Windows "is configured by default to block automatic picture downloads from the Internet," and Outlook for Mac has the same default, so a tracking pixel stays unloaded until you download pictures.
• Outlook on the web loads external images "through the Outlook external image proxy" by default, and no Microsoft page we found says whether a sender still sees the open.
• Microsoft Marketplace lists HubSpot Sales, which promises to "track email opens and clicks," and Mailsuite for Outlook, an "Email tracker for Outlook," as add-ins for Outlook senders.

Does Outlook Have Read Receipts?

Yes, Outlook has read receipts, but only some combinations of app and account can request one. Microsoft separates two kinds: "A delivery receipt confirms delivery of your email message to the recipient's mailbox, but not that the recipient has seen it or read it. A read receipt confirms that your message was opened." Yahoo Mail has no read receipts at all, as our Yahoo Mail read receipts review found.

Under the hood a read receipt request is one line in the message, a Disposition-Notification-To header. The IETF's RFC 8098, published in February 2017, calls it "merely a request" and adds that "The recipients' user agents are always free to silently ignore such a request." Here is who can send that request, per Microsoft's help pages:

• Classic Outlook for Windows: for one message, open the Options menu and tick "Request a Delivery Receipt" or "Request a Read Receipt" in the Tracking group. For every message, use File, Options, Mail and scroll to Tracking.
• New Outlook for Windows and Outlook on the web (work or school account): the same two boxes sit under Tracking on the Options tab of a message you are composing.
• Outlook.com (free personal account in a browser): "You can't request a read receipt in Outlook.com, but you can request read receipts for Outlook.com messages sent using Outlook for Windows." A note on that page adds that for Outlook.com accounts "it is only available with Microsoft 365 subscription."
• Outlook for Mac: choose Receipts, then Read Receipt or Delivery Receipt. The Mac help page limits this to "a Microsoft 365 work or school account, or an Exchange Server account managed by your organization," and rules out Outlook.com accounts.
• Outlook for iOS and Android: Microsoft announced receipts for the phone apps on March 3, 2025, starting with beta builds. You tap the + button in a draft, then the Receipts icon. The post says the feature "is available to users with an Enterprise or School account."
• A Gmail, Yahoo or iCloud account added to Outlook: no. "This feature isn't available for IMAP or POP accounts such as Gmail, Yahoo!, or iCloud."

Count the routes open to a personal Outlook.com address. Of the five apps, only the two Windows ones can send its read receipt request, and Microsoft ties that to a paid subscription. The Mac page, the phone announcement and the website all say no. GMX, by contrast, puts the request behind the Options button for free webmail accounts, as our GMX read receipts review shows.

What Does the Recipient See, and Can You Say No?

You can always say no; the apps differ only in whether they ask every time or follow a saved answer. Microsoft even advises senders to ask sparingly, because recipients who see a request now and then "are more likely to send a read receipt than if they are prompted every time that they receive a message from you."

• Classic Outlook for Windows: under File, Options, Mail, Tracking, Microsoft's page on processing receipts lists three behaviors: "Always send a read receipt," "Never send a read receipt" and "Ask each time whether to send a read receipt."
• New Outlook, Outlook on the web and Outlook.com: Settings, Mail, Message handling, then the Read receipts heading. This applies to free Outlook.com accounts too. They cannot ask for a receipt, yet they decide how to answer one.
• Outlook for Mac: a dialog appears with Cancel and Send buttons. Microsoft's screen reader guide for the Mac says "you need to decide whether to send the receipt or not for each email separately," and we found no Mac help page describing a saved default.
• Outlook for iOS and Android: a banner sits "at the top of the message" with a Send button, and "If you do not wish to send the receipt, no action is needed." The default lives under Settings, Mail, Read Receipts.

We did not open a live mailbox in each app, so these are the paths as Microsoft documents them. What a sender learns without your help is covered in Can Someone Tell If You Read Their Email?

Can an Admin Force or Block Outlook Read Receipts?

Partly: an Exchange administrator can preset the answer for Outlook on the web and filter receipts in transit, but Microsoft documents no single switch that binds every Outlook app. The pieces, from Microsoft Learn:

• Per mailbox answer: Set-MailboxMessageConfiguration takes -ReadReceiptResponse with the values DoNotAutomaticallySend, AlwaysSend or NeverSend. The scope is narrow: "These settings are applied in Outlook on the web only. Some settings also apply to the new Outlook client." They "are not used in Outlook, Exchange ActiveSync, or other email clients."
• Mail flow rules: Exchange Online rules can match on "The message type is" with the value Read receipt (ReadReceipt), and the rule actions reference includes RemoveHeader, which "Removes the specified header field from the message header." Microsoft documents those parts. It publishes no recipe for stripping Disposition-Notification-To, and we did not build one.
• Remote domains: Set-RemoteDomain has -DeliveryReportEnabled for delivery reports sent to a remote domain. Its syntax lists no read receipt parameter.

So at work the choice may not be yours. An administrator who sets AlwaysSend on your mailbox has answered for you in Outlook on the web. Phones that sync over Exchange ActiveSync follow a separate rule, and by default the server returns the receipt for them, as we explain in our Samsung Email read receipts review.

Does Outlook Block Tracking Pixels?

It depends on the app: classic Outlook for Windows and Outlook for Mac block remote pictures by default, while Microsoft's own pages disagree about the web, new Outlook and phone defaults. Microsoft separates the two mechanisms in a single line. Blocking pictures helps you "avoid tracking pixels: invisible images that can tell a sender you've read the email. (Note: tracking pixels aren't the same as a read receipt.)"

• Classic Outlook for Windows: "Microsoft Outlook is configured by default to block automatic picture downloads from the Internet," per the picture download help page. You load them per message from the InfoBar.
• Outlook for Mac: "By default, Outlook for Mac doesn't automatically download pictures or photos in email messages if the images are stored on the Internet."
• Outlook on the web (work or school): the mailbox policy setting ExternalImageProxyEnabled defaults to $true: "All external images are loaded through the Outlook external image proxy."
• Outlook.com: "Outlook.com helps protect your data by loading external images using an image proxy," says the external image protection page.
• New Outlook for Windows: we found no help page of its own. Microsoft 365 roadmap item 565862, created June 17, 2026, covers it together with Outlook on the web and describes the existing default as "load external content only for safe senders." New settings to "block all external content" were still listed as in development on October 8, 2026, with a July 2026 target.
• Outlook for iOS and Android: two Microsoft pages conflict. The consumer help page says "Images in emails are always downloaded automatically unless you (or your IT administrator) have enabled the Block external images setting." The Intune configuration guide, updated October 6, 2026, gives the app default as "Load for Safe Senders only."

The roadmap line and the policy default describe the same web app in two ways. We could not reconcile them without a test mailbox, so check your own settings.

What does the proxy hide? Microsoft frames it as a safety feature. With the proxy off, images "are loaded through the web browser," which is "potentially unsafe, as the images could have mixed content or malformed images that ask for user credentials." Nothing in those pages says whether the sender's server still gets a request when you open the message, or what that request reveals. Google is more direct about Gmail's proxy. Its image help page promises that "Senders can't use image loading to get information about your computer or location," then concedes that "Sometimes, senders may know whether you've opened an email that has an image." Microsoft's proxy pages make neither statement, so treat the Outlook proxy as unproven for hiding opens.

Does Microsoft Offer Senders Open Tracking?

Yes, in three places we could verify, and none of them is the Outlook compose window.

• Dynamics 365: Microsoft's email engagement documentation says Dynamics 365 Sales "generates a uniquely named, transparent, one-pixel GIF and adds it to the message as a linked image." The marketing product, Customer Insights - Journeys, "adds an invisible pixel to HTML messages." Our Dynamics 365 tracking review has the hostnames and the consent rules.
• Viva Insights: this Outlook add-in shows a sender the open rate of mail sent to coworkers, with no pixel involved. The Viva Insights privacy guide explains: "When Outlook marks an email as 'read,' that information is saved within the person's mailbox, then delivered to the sender's mailbox if that person has opted in to using Viva Insights." That is the mailbox's read state, not an image request. It covers mail to five or more people inside the same company and "doesn't show information about individual recipients."
• Third party add-ins: on October 8, 2026, Microsoft Marketplace listed HubSpot Sales ("Organize leads, track email opens and clicks, and send email templates all in one place.") and Mailsuite for Outlook ("Email tracker for Outlook. Free and unlimited email tracking."). We read the listings and did not install either.

Put the two mechanisms side by side. The read receipt is the one Microsoft restricts by account type and hands to the recipient for approval. The pixel asks nobody, and it installs from Microsoft's own store.

How to Turn Off Outlook Read Receipts and Block Pixels

Each Outlook needs two changes, one for receipts and one for pictures. The steps below use Microsoft's labels; our Apple Mail and Outlook walkthrough goes deeper on the image settings.

Classic Outlook for Windows

1. Select File, then Options, then Mail, and scroll down to Tracking.
2. Choose "Never send a read receipt," or "Ask each time whether to send a read receipt" if you want the prompt.
3. Go to File, Options, Trust Center, Trust Center Settings, and open Automatic Download.
4. Leave "Don't download pictures automatically in HTML e-mail messages or RSS items" ticked. Microsoft notes that clearing the first option there means "all pictures will be automatically downloaded."

New Outlook, Outlook on the web and Outlook.com

1. Select Settings, then Mail, then Message handling.
2. Under Read receipts, pick the option that never sends a response.
3. In Outlook.com, open Privacy and data in Settings and keep "Always use the Outlook service to load images" selected. That page offers only this and "Don't use the Outlook service to load images," so it documents no way to block every image.

Outlook for Mac

1. On the Outlook menu, select Settings, then Reading under Email.
2. In the Download external images section, choose "Ask before downloading."
3. When a read receipt dialog appears, pick Cancel. These labels come from Microsoft's Mac picture settings page, which warns that "Support for legacy Outlook for Mac will end in October 2026."

Outlook for iOS and Android

1. Open Settings, then Mail, then Read Receipts, and set your default answer (work or school accounts).
2. Find the external images setting and choose "Block external images." Microsoft's help page names the setting without giving its location.
3. Expect a gap when you reply: the block "only applies to the email reading pane."

Tools and alternatives

• Trocker: a free browser extension whose Chrome Web Store listing names "Gmail™, Yahoo! and Outlook.com" as supported webmails and notes added support for outlook.cloud.microsoft. It shows 10,000 users and a July 10, 2026 update. We did not test it in Outlook.
• Gblock: a paid desktop Chrome extension that runs only on mail.google.com. It does nothing inside any Outlook app, including Outlook on the web.

What This Means If You Also Use Gmail

If you read work mail in Outlook and everything else in Gmail, the two mechanisms behave differently when they cross that border. A read receipt request from an Outlook user gets no answer from a personal Gmail account. Google's read receipt help page says: "Read receipts are only available to work or school accounts. They don't work with personal Gmail (@gmail.com) accounts." The reverse fails too. Add your Gmail account to Outlook and Microsoft says receipts are not available for it. Our explainer on how Gmail read receipts work has the Workspace side.

Pixels cross without trouble. A tracking pixel from an Outlook sender is an ordinary remote image wherever it lands, and Gmail's default is to show images: "By default, when you get an email with an image, you'll see the image automatically."

This is where Gblock fits. It works in Gmail on desktop Chromium browsers, where it blocks known tracking pixels while other images keep loading and strips tracking from links. It does not run in Outlook, in the Outlook phone apps, or in any desktop mail program. For the Outlook half of your mail, the native settings above are the tools you have. Our Gmail tracking blocker comparison tests the Gmail options side by side.

The Quick Answer

Does Outlook have read receipts? Yes, for work and school accounts in every app, and for a personal Outlook.com account only from Outlook for Windows with a subscription. Can you refuse an Outlook read receipt? Always, unless an administrator has preset the answer on your work mailbox. Does Outlook track your email? We found no page in Microsoft's Outlook help describing a pixel that Outlook itself adds to ordinary mail. Senders bring their own, through Dynamics 365 or a marketplace add-in. Classic Outlook for Windows and Outlook for Mac stop those pixels by default. For the web and phone apps Microsoft's pages conflict, so open your settings and look.
