Alias verification link not working

I've got quite a few aliases to my Outlook.com account set up and verified without issue. However there is one alias I have that, when I click 'verify' and get the verification e-mail, the link w/in the e-mail doesn't work.

I click the link and am first met with a "server temporarily unavailable" page, then clicking the link again tell me the link is expired or invalid. After this point, I continue to get the expired/invalid message, and the alias remains unverified.

I'm curious to know what I can do to get this alias verified. Let me know what information you need to make this happen. Thanks.
