Glad I could help. I can understand wanting to just have a new "from" address. Outlook/Hotmail does support that. That's the alias concept (https://account.live.com/AddAssocId?fl=nd). I think the Outlook upgrade flow might offer that as well, but I'm not sure.

One big missing feature is the ability to rename to an existing alias. That would have fixed your issue as well. I believe that this is "kind of" supported, but I've never tried it. You can delete an alias and then immediately rename to that address. No one else will be able to grab it for 6 months, but if you've added a bunch of aliases, you might be in a "no new alias" window, and I think in that case your rename action might fail (or might not; I'm not sure and unwilling to break my account trying. :)).
