The comedian announced last year that he will depart his role as bumbling boss Michael Scott when his contract expires at the end of the current season.
However, Greg Daniels recently told Fancast that viewers can "absolutely" expect to see Carell make the occasional guest appearance in the future.
"That might be a hint that [Michael Scott] is not being murdered," he quipped.
Daniels also admitted that he was nervous about replacing Carell, but added: "I think there is just as much danger in not changing anything and just... slowly going along on a track."
"It is actually sort of exciting. The remaining cast will be put into new positions. They will be bouncing off new people and they will have to fight for attention again."
It was previously confirmed that the character of Scott will depart the show prior to the seventh season finale.
The Office airs on Thursdays at 9/8c on NBC.
