Senior Undersecretary to the Minister for Magic's office

This office belonged to the Senior Undersecretary to the Minister for Magic and later, during the puppet administration of Pius Thicknesse, it served as the office for the Head of the Muggle-Born Registration Commission. The only known person to have been in these positions, and thus to have used this office, was Dolores Umbridge. It was found on Level One of the Ministry of Magic as part of the department of Minister for Magic and Support Staff.

Description
While belonging to Umbridge, it was decorated it as she had decorated her office at Hogwarts. It's walls were made of pink-grey porcelean tiles, it had lace drapes, doilies, and dried flowers covering every available surface. On the walls, there were plates which had a uniquely painted cats on each one. There was also a highly polished desk which had a flowery cloth covering it. In the desk there were quills, ink and Spellotape; enchanted paperclips that coiled snake-like around the drawer; a fussy little laced box containing spare bows and clips; also a little box containing pink paper with small cats at the bottom.

Muggle-Born Registration Commission
During the puppet administration of Pius Thicknesse, this office also served Dolores Umbridge in her capacity as Head of the Muggle-Born Registration Commission. In this capacity, the office contained a filing cabinet behind the desk that Harry compared it to the one in Filch's office. It contained various files with the names of various workers at the Ministry. During this time, the office also contained a telescope attached to Alastor Moody's magical eye which Umbridge used to spy on the workforce in the outer office. Inside the desk were the books When Muggles Attack and Mudbloods and How to Spot Them by Barrett Fay, as well as The Muggle Conspiracy by Sinistra Lowe, though these books may have also been present during Umbridge's tenure as Senior Undersecretary and not just during her time as Head of the Muggle-born Registration Commission.

Later occupants
It is unknown what use this office came to after Umbridge was removed from power; it was likely occupied by the next Senior Undersecretary to the Minister.
