Microsoft Teams displays a blue double checkmark under each private message by default as soon as the recipient opens it. This mechanism, known as read receipt, only works in private (one-on-one) conversations and in restricted groups. It does not trigger in team channels. Understanding this mechanism is the starting point for knowing when your read status is visible, and when it is not.
Disable read receipts in Teams settings
The most direct method to read a message on Teams without the sender knowing goes through the app’s native settings. In the desktop client or mobile app, go to settings, then to the Privacy section. You will find an option titled “Read receipts”.

Turn off this toggle. The effect is immediate and bidirectional: you no longer generate a read receipt, but you also no longer receive one. The sender will only see the “Sent” checkmark, never the “Read” checkmark.
One technical point deserves attention: the administrator of your Microsoft 365 tenant can enforce the activation of read receipts through a messaging policy. In this case, the toggle in your settings appears grayed out, and you cannot change it. Before looking for workarounds, check if your organization locks this setting. To delve deeper into this topic, you can read a Teams message without being seen thanks to Portail Patrimoine, which details the different scenarios.

Notification preview and offline mode on Teams
When deactivation is not accessible, two techniques exploit the normal functioning of the application without triggering the read receipt.
Read via the notification banner
On both Windows and macOS, Teams displays a pop-up notification when a message is received. This banner contains the first lines of the text. Reading the message from this banner does not trigger any confirmation, as you do not open the conversation.
The limitation is obvious: only short messages can be read in full. For long messages, you will only see a snippet. On mobile, the principle is the same with banner notifications or on the lock screen.
Switch to offline mode
The second technique involves cutting your network connection (Wi-Fi or mobile data) before opening the conversation. Teams allows you to view messages that have already been synchronized locally even without a connection. The read receipt cannot be transmitted to Microsoft servers as long as you remain disconnected.
Then completely close the application (not just minimize it), and then restore the connection. The exact behavior depends on the client version: in some recent updates, Teams may send the confirmation at the time of reconnection. This method is therefore less reliable than deactivation in the settings.
Teams messaging policy and administrator control
Microsoft 365 administrators have a direct lever on read receipts through messaging policies in the Teams admin center. Three configurations exist:
- Receipts enabled for all users, with no option to disable them individually. The “Read” checkmark always appears.
- Receipts disabled for the entire organization. No user sees or generates a receipt.
- Option left to each user’s choice, who can then enable or disable the setting in their privacy settings.
This granularity explains why the same trick works in one company and not in another. The administrator setting always takes precedence over individual choice.
Digital trust clauses and corporate agreements post-2026
The issue of discreet reading on Teams goes beyond just a technical setting. Since the CNIL report published in March 2026 on digital surveillance in companies, and the decision of the CJEU (case C-452/24, rendered in February 2026), the legal framework surrounding collaborative tools has tightened.
Many corporate agreements now include digital trust clauses that explicitly regulate the use of read receipts. These clauses define whether the employer can impose their activation, and under what conditions employees can refuse them.
Bypassing a read receipt imposed by a messaging policy may constitute a violation of these internal agreements. The nuance is as follows: disabling the setting when it is accessible in your settings is an intended use by Microsoft. Using technical manipulations (airplane mode, third-party apps) to bypass an administrator lock falls under a different logic.
- Check if your corporate agreement or IT charter mentions read receipts and messaging tools.
- If the setting is locked by administration, deactivation is not intended for you: bypassing it exposes you to disciplinary risk.
- If in doubt, the GDPR gives you a right to information about the tracking data collected via Teams. Address the question to your DPO.
What Teams never reports to the sender
Not all interactions on Teams generate a visible trace for the sender. Some actions remain invisible by design:
Reading messages in a team channel (as opposed to a private conversation) does not produce any read receipt. The sender does not know who has seen their message, unless they use a poll or a third-party feature.
Reactions (emojis) added to a message signal your presence, but simply hovering over a message in a channel leaves no trace. Similarly, viewing shared files in a conversation does not trigger the “Read” checkmark on the associated message.
The last point to keep in mind concerns the update to version 2.15 of Teams, reported on the Microsoft Tech Community forum: a partial marking as read may trigger after a few seconds of display, even without explicit user action. The rules of the game evolve with each update of the Teams client, which makes any workaround potentially obsolete overnight.
