> Both emails encouraged me to contact customer support. I did so only to be met with a request to fill out an online form with an incredible amount of personal information to verify the account. Why would I provide 10X the personal info (...)?

This by itself looks like a phishing attack. Did you click a link to Skype support in the second email message or find it by yourself going to the Skype website and browsing around?

Also very confident that this is a phishing attack, have received similar emails for Office 365 as well. If you examine the email headers you'll notice a suspicious "From:" address.

This was my thought, too, but then I remembered that Blizzard asked me for a photo of a government issued ID card to delete my Battle Net account for some reason, and no, that wasn't a phishing attempt; it's in their documentation: https://us.battle.net/support/en/article/2659

So, maybe it could be legit.
