CNET reports Microsoft has started early outside testing of some of the server elements that will end up in Office 14:
The software maker did not offer details or say when a test version of the software, code-named Office 14, will be made more broadly available.
"Today Microsoft provided a select group of customers early access to an Alpha version of Office server technologies," the software maker said in a statement. "However, Microsoft is not disclosing information about the timing for a Beta version at this time."
Microsoft has also begun testing for the next version of Exchange, code-named E14.
