Fred is right that -mi estimate- does not yet officially support -xtmixed-.
However, -mi estimate- provides a way of obtaining results from virtually any
estimation command via option -cmdok-.  For example, you can type:

. mi estimate, cmdok: xtmixed y x1 i.x2 || group:

to obtain MI results from -xtmixed- with factor variables.
