Single-Line View - NEW Outlook

Posting this here since the massive thread I just read through has been closed to replies, yet the issue persists... Getting New Outlook to display messages in single-line view

No, there is no setting (in NEW Outlook) for the messages pane to always be single-line (annoying).

Yes, I know you can drag to resize and, at a certain width, it will switch to single-line view. BUT, I'm having to drag so it's HALF the width of the window before it will switch to single-line view. That makes the reading pane too narrow (I need the calendar pane open on the right, so can't hide that to make more space).

Even if I didn't mind that it had to be half the width of the window, there's all this empty space on the right side of the messages pane that I can't fill. I can't drag the from or subject columns to make them wider (only narrower, increasing that empty space on the right). I also can't drag the date column to make it wider at all, even though there's room, so I can't read the full dates or times.

That last bit has to be a bug, right? Does anyone know how I can actually contact MS or file an official feedback on this? (And the annoying yellow highlight, but I won't get started on that.)

I'm stuck using old Outlook because of this, much to the chagrin of the IT department at work.

This is what my old Outlook looks like (see how the messages pane doesn't have to be half the screen?):

I'm not a new-design hater. I actually like the cleaner, more modern look Outlook and a lot of other apps are using. But it's come at the expense of functionality, and that is unfortunately more important than looks.

Dear @Sarah Martin,

Thank you for reaching out to the Microsoft Q&A Community.

I want to apologize for the challenges you are facing with the new Outlook interface. I can confirm that I've been able to replicate a similar issue in our test environment. You are absolutely right, the problems you've described with the single-line view are not isolated, and many users have expressed similar concerns.

Based on our checks, the behavior you're seeing is a combination of a deliberate design choice and what appears to be a bug.

  • The need to shrink the messages pane to a specific width to activate single-line view is part of the new responsive layout. While intended for adaptability, it can be a source of difficulty for users who require a specific screen setup.
  • The inability to resize the columns to fill the empty space is an issue we've noted as well. Your screenshots clearly illustrate this point, and it's something that needs to be addressed.

Filing official feedback is the most effective way to influence product changes. Your detailed experience is invaluable to the product team, and they actively review feedback to prioritize improvements.

I strongly recommend you submit your experience through these official channels:

In-App Feedback: In the new Outlook desktop app, go to the "Help" tab, click "Feedback," and select "Report an issue."

I can't stress enough the importance of your feedback in this scenario. This is a common concern for many users. I strongly recommend that you share your detailed experience and feedback directly with the Microsoft product team through their official feedback channels. This is the most effective way to make your voice heard and influence future feature improvements and adjustments.

You can visit the Outlook · Community to submit a new idea or vote on existing one. Our product team is in charge of the site, and they constantly check customer reviews and feedback. The higher votes, the more attention the related team will pay on, and a lot of the features are developed and improved based on customer feedback. As a moderator, I will also pass along your feedback to the appropriate team for further consideration. While we don't directly influence product design, user feedback is actively reviewed and helps prioritize future development.

Here are a example draft for your feedback:

Single-Line View: Wasted Space and Inability to Resize Columns in New Outlook

When using the new Outlook with the messages pane in single-line view, there are significant usability issues. The current behavior makes the application feel unresponsive and inefficient.

Here are the specific problems I am experiencing:

  1. There is no dedicated setting to force the single-line view. The messages pane must be manually dragged and resized to less than half the window's total width for the single-line view to activate.
  2. This requirement forces the reading pane to be extremely narrow, making it difficult to read messages, especially when the calendar pane is also open.
  3. Even when the single-line view is active, there is a large amount of wasted empty space on the right side of the messages pane.
  4. The "From," "Subject," and "Received" columns cannot be resized to fill this empty space. I can only make them narrower, which makes the problem worse.
  5. I am unable to resize the "Received" column at all to see the full date and time. This seems to be a bug, as there is plenty of room.

These issues are a significant step back from the functionality of the classic Outlook. The inability to control column width and the wasted screen space severely impact my workflow and make me unable to use the new version effectively. Please consider adjusting the design to allow for a more flexible and efficient single-line view.

I will personally vote for your feedback to help it gain traction and hopefully, Microsoft will make improvements soon. 

I really understand how disruptive and frustrating this kind of issue can be for your workflow. We appreciate your kindness and understanding as we deal with these evolutionary product changes. Please get in touch if you need anything else.

As other users will also search information in this community, your valuable vote will definitely also help other users who have similar queries easily to find the correct channel and useful information more quickly.
