Word's column feature does not work within a text box. You don't say which
version of Word you're using (Windows and Word are *not* the same thing),
but later versions of Word support floating tables that can be moved much as
pictures and text boxes. By using a two column table, you might be able to
get what you want. Or, if you need text to flow from one column to the
other, you might use two text boxes side by size, and use the link tool to
cause text to flow from one text box into the other.

Word doesn't support multiple column text inside text boxes or frames.

As a workaround, make two text boxes positioned side by side. With the
cursor in the first box, click the Create Text Box Link button on the
Text Box toolbar, then click inside the second text box. That makes
text "flow" from the first box to the second box automatically. Format
each box with No Line so it isn't obvious that they're separate.

A less desirable workaround is to place a two-cell table inside a text
box. You'd have to move overflow text manually from the first cell to
the second cell. This might be feasible if the text would never be
edited afterward.
