The Office suite has long been rumored to be coming to the iPhone and iPad, but Microsoft has been mum on any official plans for offering the software on Apple devices.
However, according to a ZDNet report citing sources close to the matter, Microsoft is in no hurry to launch an app on other platforms. In fact, it has been using the Office suite—which includes programs such as Word, Excel and PowerPoint— as leverage to entice people to buy Microsoft's own Surface tablet.
The tactic isn't paying off. In fact, the company is losing a lot of money by not offering its products on other platforms, said Adam Holt, an analyst at Morgan Stanley,
In February, Holt said in a note that Microsoft was leaving about $2.5 billion a year on the table by not being on the iPad.
CNBC asked Microsoft for comment on plans for releasing Office on other platforms but did not immediately hear back.
