Microsoft Corporation has pushed back the retail release of Office 2000 a few weeks to June 4th. Technically, this isn't much of a slip: The company has said repeatedly that Office 2000 would be finished sometime in Q1 1999 and would appear in stores sometime in Q2, so this does still meet that schedule. Still, retailers were originally expecting to see Office in mid-May and the move forces them to cancel advertising campaigns that would have launched then.
