The now-$4.4 billion contract was originally awarded to General Dynamics IT in August 2019, before two Perspecta protests sent GSA and DOD back to the drawing board.

General Dynamics IT, Dell and Minburn won the cloud collaboration and email services contract in late August through a teaming agreement.

It's no secret that the DOD likes Windows 10. One software contract is worth up to $3.17 billion, and another enterprise services deal could bring Microsoft $1.76 billion.
