Once old Skype account is connected with Microsoft Account it can't be separated; if I'm not mistaken it was possible to disconnect both shortly before MSN/WL Messenger was terminated completely. I did log into Skype recently on my old forgotten accounts - one I was using on daily basis and other I tried to delete because of unfortunate username (no response of course happened from Skype back then; leaving account to rotten for period of over 365 days didn't do a thing). Both were working without problems (tho, chat history was gone as they announced), not connected with any Microsoft Accounts. And honestly, MSN Messenger was the best service MS provided - sans that short time when it was the annoying Windows Messenger bundled with XP
