How to Open Emails in Separate Window in New Outlook

Currently, none, unfortunately.

Agreed, Mark. I gave up on the new Outlook and reverted to the current version. The new version of Outlook is like trying to run a business on a child's toy and has absolutely nothing to offer. It is email software that appears to have been created by people who have never used email before. The lack of basic functionality compared to every other current email interface (including Outlook's current version) is egregious - users can't even choose where to save a file beyond OneDrive or Downloads, which is absurd. I don't know why anyone would choose to use the new Outlook in its current state or why Microsoft continues to insist on creating software that is different but not better, and disruptive to the user experience while failing utterly to improve it. Offer users a preview that improves workflow or leave Outlook as-is.

I have found one feature in the "new" outlook that I like (and can't find in the current outlook). You can pin emails so that they are always on top. Outlook 365 on my Mac has had this for a while AND still opens emails in a new window.

This is the second time I've tried the new outlook on W11. Until Micro$oft forces me to go, I'm sticking with the old one.

I do not have either of these option with my mail, there are no setting showing at all!

Hey Ricky, my IT team pushed the new version, I had no choice and still confirming if I can go backwards. So MS should fix the problem. That's the best solution here.
