Configuring preferences and options in Outlook.com
What an unhelpful response! I have been looking for the answer to this question, as well. I have found multiple Microsoft documents that allege to be able to lead you to a solution, all of which end up in a dead end. And for you to respond with basically "Not my job" is unacceptable. Either the feature exists or it doesn't. And the fact that you don't know whether it exists or not shows the true limitations of your product knowledge. Once again Microsoft Support is a disappointment.
