Quit trying to be Gmail!!! There is a REASON we use Outlook and not Gmail. The conversations feature is an absolute beat down - especially with a fairly lengthy group conversation. I mean, I'd rather have my toenails ripped out than try to find my last comment in a thread like that. At the very least, let us disable this mostly copy-cat feature. Innovate, for once. Come up with something new and unique. If it's going to turn into Gmail, let us know. I'd rather just move to Gmail since they clearly do "their" thing better than you will. But the conversations is a deal breaker for me.
Thanks for the feedback, and thanks for using Outlook.com. I just wanted to let you know that you are able to disable conversation view from the beta.
Here are the steps
1) From within the Beta, Click the gear at the top right.
2) This will open a Panel on the right and you should see Conversation View settings. There are three. The first is Newest on Top, Newest on Bottom, and finally Off.
If you select Off you will not have to interact with conversations again :)
Hope this helps, and thanks for the great feedback!
