How to Disable single click to open email in New Outlook?

I just found this issue too (now moved to using the web based mail only).

My conclusion so far until they fix it, instead of single click, right click and go direct to the options I was probably after anyway.

I single click because I want to delete/Mark Read something without reading, and found these options are immediately availavle in the right click menu

I used the following approach as workaround:

1. Go to Settings >> Mail >> Layout >>
2. Under the Reading pane options, select "At the bottom"
3. Save and return back to email list window. Reading pane at the bottom half will appear.
4. Drag the Reading Pane border marker (top-right) to reduce the size of the pane to minimum possible.
5. Now the single click will not open any email. Whereas double click will open the email in new window.

Thank you, this has been so frustrating, closing an email, then also closed outlook as a whole with this 1 click rubbish!

I want to use the new version of Outlook however they need to add this option in as I don't like the fact the email opens in outlook when you click on it.

Hoping Microsoft put this feature back in as we are going to need this for people to adopt this new version.

Frustrating I can't get on with the new outlook as the copilot stuff looks good and doesn't work well with the old outlook.

Come on Microsoft put this feature back in please.

Having the same issue, and not able to turn this option for a single-click. Posting reply to bump this back to the top.

Each rendition of the new outlook is getting better, but I'm kind of getting tired of having to revert back to the old version each time I hit a snag, that did exist in the older versions, but doesn't exist (intentionally removed?) in the new version.
