Our sources at Microsoft have confirmed that Office for Mac 2011 will be available as a download for Microsoft Developer Network (MSDN) and TechNet subscribers. This will be the first time Office for Mac has been offered by either of these services.
MSDN and TechNet are two subscription-based services from Microsoft, similar to the Apple Developer program. MSDN provides resources for developers using Microsoft products and TechNet provides resources for Information Technology (IT) specialists supporting Microsoft products.
Subscribers should see Office for Mac 2011 available for download around October 26, which is its official launch date. The software will be available on disk at a later date to be determined.
Microsoft has no plans to offer earlier versions of Office for Mac through these services.
