Microsoft criticized Delta Air Lines on Tuesday for overstating the tech company’s role in a costly disruption that led the airline to cancel thousands of flights.

Microsoft has accused Delta of ignoring offers to help with recovery from the massive Windows outage last month in part because its IT systems were allegedly outdated.

The software company said in a letter that Delta Air Lines had falsely blamed Microsoft for its decision to cancel thousands of flights after a tech outage.
