If you haven’t yet had your fill of Microsoft betas, also known as Insider builds, and use the Outlook.com website, you can join the Outlook.com beta. This is an opt-in web experience, giving end-users the ability to try out “new product innovations” and share your experience with the Outlook.com product team. Microsoft will use the feedback to improve, refine, or discard the new features. When it's over, the best innovations will make it into Outlook.com.
If you want to be on the cutting edge (or are a glutton for punishment), click the ‘Try the beta’ toggle switch when it shows up in the top right corner of your Outlook.com Inbox. It’s rolling out in waves and if it's not there now, it will be within a few weeks. (You might want to try a different browser too, my account has it available in Chrome but not in Edge.) If you don’t like the new design, you can switch back to the regular web site at any time by sliding the toggle to the Off side.
Leave your suggestions or comments at the Outlook.com beta site on UserVoice.
One of the features enabled in the beta experience is Photo Hub, where all of the photos in your mailbox (sent or received) can be viewed in one place.
Hover over a photo to see the sender's name, message subject and a link to the original email message thread.
BTW, I’m just kidding about being a glutton for punishment. The features they enable for beta users will be solid. it’s down to whether you want to see the new features ahead of everyone else or hate change and want to keep the old stuff around as long as possible.

The beta looks nice! Hopefully the beta will allow users to completely & permanently delete messages. It would be awesome to avoid the redundancy involved with deleting messages twice (i.e.: the dreaded recover deleted messages). I also hope the beta will fix the problem associated with
tags and whatnot. I use the web version (Outlook.com) to send & receive email. I get a paragraph (i.e.: double blank line) by pressing the enter key twice. I have tried multiple browsers (IE, FF & Chrome)...same problem with all of them. You do not see the double line until you receive a reply from the recipient using gmail, yahoo, or just about any other provider. It sucks to have to hit "shift-enter" all the time. It's not natural for anyone to do that. Please remember, this comment pertains to Outlook.com...accessed through a browser. I'm thinking about switching to gmail at this point.
