Hello,

After I inadvertently clicked on the right side bar where says,
Go beyond email with
outlook.com
upgrade now for free
automatically switched me instantly to outlook.com

I was in the middle of composing an email so I clicked the back button and finished composing.
After clicking send it switched to outlook.com
I found the gear icon and switched back to standard Hotmail.
That is when my inbox started to "Group messages by conversation"

Why did my Hotmail inbox revert to "Group messages by conversation" after this happened?
Is there away to permanently eliminate this ad side bar? The clicking area it quite large and is easy to inadvertently click on.

Thanks
