Dunder Mifflin Sabre was a corporate division of the printer company Sabre and workplace of most major characters of The Office from its establishment in the Season 6 episode Sabre until its dissolution in the Season 8 finale Free Family Portrait Studio. Although the exact number is unclear, multiple branches of the division existed since its inception, most notably Scranton. The Scranton branch of the division was first managed by both Michael Scott and Jim Halpert, who served in co-managerial roles before Dunder Mifflin Paper Company's merger with Sabre. Michael Scott assumed the role of sole manager of the Scranton branch, later succeeded by Deangelo Vickers, Andy Bernard, and finally Nellie Bertram, who served as the branch's last manager before Sabre was liquidated and the division ceased to exist.
Dunder Mifflin Sabre was created after the Dunder Mifflin Paper Company faced bankruptcy and deep financial turmoil. Sabre's acquisition made the Dunder Mifflin Paper Company a subdivision of the printer company, allowing most major characters of the show to retain their jobs. The Dunder Mifflin division was ultimately subordinate to Sabre, headquartered in Tallahassee, Florida. The Chief Executive Officer (CEO) of Sabre, first Jo Bennett and later Robert California, assumed a supervisory role of the Dunder Mifflin division, particularly its most successful branch in Scranton. Apart from the provisional employment of Gabe Lewis by the Scranton branch as a corporate liaison to Sabre, the Dunder Mifflin division of Sabre very much carried out its operations as it had before the merger, with most changes centering on its adoption of a printer selling program that was eventually phased out in favor of preexisting sales goals.
The erratic leadership style of then-CEO Robert California at the end of Season 8 convinced former employee Andy Bernard to pursue an investor to buy out the Dunder Mifflin Paper Company. David Wallace, former Chief Financial Officer (CFO) of Dunder Mifflin Paper Company, agreed to buyout the Dunder Mifflin division of Sabre, a move after which Sabre ceased to exist. Dunder Mifflin Sabre was dissolved in favor of the Dunder Mifflin Paper Company, which existed in its third incarnation for the entirety of Season 9 until the series' conclusion.
