Configuring preferences and options in Outlook on the web for business
Hi,
Thank you for posting in Microsoft Community.
It looks like on your Microsoft 365 Outlook, emails are being Marked as Read even by being previewed or being replied. I totally understand the importance of having this clarified as soon as possible. Let's work on this together in finding the best possible answer to your concern.
To better understand the situation, I would like to ask some question, such as:
- What Microsoft 365 version & edition are you using? provide us a screenshot of your product information About Office: What version of Office am I using? - Microsoft Support
- Kindly resend us the screenshot on your original post to have a better picture of the situation. There might be a minor system glitch when you are about to submit your post.
After further research, it looks like in Microsoft 365 Outlook, you can change the settings to mark an item as read only after you open it. Take note, this is only applicable using the Outlook application. Here's how:
- Click on the "File" tab in the top left corner of the Outlook window.
- Click on "Options" in the left-hand menu.
- In the Outlook Options window, click on "Advanced" in the left-hand menu.
- Scroll down to the "Outlook panes" section and click on "Reading Pane".
- In the Reading Pane settings, select "Mark item as read when viewed in the Reading Pane".
- Uncheck the box next to "Mark items as read when viewed in the Reading Pane for (n) seconds".
- Click "OK" to save the changes.
This should ensure that an item is marked as read only after you open it, and not when you preview it or move the selection. I hope this helps!
Sincerely,
