Pat Fox of the Office for Mac team wrote on the company's official blog this week that inquiries about those features have been the "most common question" for users of late. The Microsoft team is said to be "working hard with Apple" to enable the features.
"I know your next question will be 'when?', and unfortunately I can't answer that -- but it's likely measured in months not days -- just to set expectations," the post reads.
The news came alongside the release of an update to Communicator for Mac, which addresses an issue related to crashing in Lion. The download is available through Microsoft AutoUpdate.
The company also reiterated that Office for Mac 2004 will not ever work on Lion, because the software was a PowerPC-based product, and Lion no longer includes Rosetta.
"Now would be a great time to upgrade to Office for Mac 2011 if you're upgrading to Lion!" Fox said.
Office for Mac 2011, the industry's most popular productivity suite, was released last October, delivering better compatibility with the Windows version of Office and corporate server products. It also features a revised user interface that's similar to the "ribbon" interface used in Windows.
Those user interface elements are built on Cocoa, the development layer of Mac OS X. And the all-new version of Outlook that shipped with Office for Mac 2011 was also built from the ground-up with Cocoa for the Mac.
File versions, auto-save and full-screen are major features touted as part of the newly released Mac OS X 10.7 Lion operating system. With support for Lion, documents are automatically saved, and multiple versions of the file are stored allowing for Time Machine-like recovery of previous iterations of a file.
The new full-screen support in Lion also brings an iPad-like feel to the operating system, allowing users to concentrate on one task at a time and quickly swipe between full-screen applications with a multi-touch gesture.
Apple's own competing productivity suite, iLife, was already updated for Lion earlier this month. iWork Update 6 adds support for full-screen mode, resume, auto-save and versions to Pages, Numbers and Keynote.
