Microsoft said Tuesday that it has begun early outside testing of some of the server products that will make up the next version of Office.
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.
News of Office 14 testing was reported earlier Tuesday by ZDNet's Mary Jo Foley.
