U.S. stock indexes were set for a mixed open on Thursday as shares of Microsoft fell after the company lowered its profit forecast, offsetting relief from a pullback in oil prices that eased worries about rising inflation.

The ADP National Employment report showed private payrolls rose by 128,000 jobs last month, far below estimates of 300,000 jobs, and a decline from the downwardly revised 202,000 in April.

All eyes will be on the nonfarm payrolls report on Friday, with economists expecting the economy to have added 325,000 jobs last month.
