Rumor has it Microsoft is again toying with the idea of purchasing Yahoo. The Redmond, Washington-based company may partner with another unnamed firm in an effort to make a bid, an anonymous Microsoft executive told Reuters on Wednesday. However, Reuters noted that other divisions inside Microsoft are still not sold on making an offer on the troubled search engine. AllThingsD said rumors about Microsoft’s interest are not true and that the company is not currently interested in acquiring Yahoo. Several other companies are said to be interested in purchasing Yahoo, which recently fired its CEO Carol Bartz, including DST Global, Providence Equity Partners, Alibaba, Hellman & Friedman and Silverlake Partners. Microsoft made an offer for Yahoo in 2008 before cutting off all discussions.
