Alliance/Hot Girl/Office Olympics/The Fight/The Secret/The Carpet/Drug Testing/Grief Counseling lady
In the episode The Alliance, a red-haired woman is seen at Meredith's birthday celebration. She is also briefly seen in Hot Girl. During the closing ceremonies for Office Olympics, the same woman, now with gray hair, is seen applauding. In The Fight, she can be seen leaving the office at the end of the day. In The Secret, she can be seen cleaning her desk (just outside the break room facing Toby's desk) when Jim joins Pam in the kitchen to tell her he no longer has a crush on her. In The Carpet, she can be seen working at her desk when Jim is trapped in the kitchen. In Drug Testing, she can be seen working at her desk as Dwight discusses his green urine. She is also very briefly seen in Grief Counseling. Although there is no solid evidence to suggest it, many fans have linked her to possibly being Marjorie.
Alliance warehouse worker
Basketball warehouse worker
In the episode Basketball, this unknown Asian warehouse worker is seen in the background frequently.
Sexual Harassment warehouse worker
These two females were frequently seen at the Stamford branch before its closing. The African-American woman appears to be the Stamford receptionist.
The Merger Stamford employee
In the episode The Merger, this unknown character is seen sitting next to Andy on the table in the conference room. Considering all the Stamford employees were told to sit on the table, it is assumed he was once an employee at Stamford. This character, however, is never seen again.
Safety Training warehouse worker
In the episode Safety Training, this never-before-seen Asian warehouse worker is frequently seen in the background. It remains to be seen if he will continue to appear.
