How is this still "Under Review"? It seems silly that you can't even do a basic function that was designed back in 1995 (mIRC)... at least skype conversations saved in Outlook for previous reference and now it is literally a long text message (except a lot longer since you IM each throughout the day). Talk about a huge fallacy on MicroSoft's part.
