Organizing and accessing contact information in Outlook.com
outlook.com has recently dropped the ability to edit a distribution list on the fly for individual messages. the dist list name used to present a + sign in front of the list name. the + sign allowed you to modify the list for only that particular email.
right click viewing and editing looks like you'd change the original official list permanently; not what is needed for this temporary, one off mod that is needed so frequently.
the beta version has kept the + functionality but the mainstream version has dropped it.
this functionalty needs to be returned as it is very useful. this change to functionality occurs with all the different browsers I use.
