However, neither has said a word about ending the company's US$19.4 million contract with ICE.
US President Donald Trump signed an executive order on Wednesday cancelling the separation policy for the next 20 days. About 4000 children have already been taken from their parents and there is no sign of their being returned.
About 100 employees had sent a letter to Nadella, asking for the contract with ICE to be cancelled.
"Our current cloud engagement with US Immigration and Customs Enforcement is supporting legacy mail, calendar, messaging and document management workloads," he wrote.
Smith's post dealt with two pieces of legislation which the US Congress is to vote on soon: the Securing America’s Future Act and the Border Security and Immigration Reform Act of 2018.
He outlined the provisions in each bill which Microsoft supported and aspects of each that it found troublesome.
The employees had asked Nadella to:
- "Cancel the existing Azure Government contract with ICE immediately.
- "Draft, publicise, and enforce a clear policy stating that neither Microsoft nor its contractors will work with clients who violate international human rights law.
- "Commit to transparency and review regarding contracts between Microsoft and government agencies, in the US and beyond."
Nadella did not deal with any of these concerns in his post. Neither did Smith.
