NBC's The Office comes to an end this spring after nine seasons of following the lives of a group of quirky Dunder Mifflin employees.
In an interview with Access Hollywood, Krasinski said he is confident that all of The Office's characters will get the proper closure.
"I think [fans] will go away satisfied because of the bar that has always been set by these characters, which is... a reality that is not only believable and romantic, but at the same time very real," he explained.
The actor continued: "You'll experience things with these characters that you've either experienced yourself or have heard of people experiencing, so there will be a familiar feeling with what we go through that I think that attachment will allow you to be a part of something with us, and not just by yourself."
Krasinski also revealed which Office props he hopes to take with him when the series wraps.
"It's so mundane, but I really want the Assistant Regional Manager Jim Halpert [sign] because it will always remind me of that fight with Dwight about 'Assistant Regional Manager' vs. 'Assistant to the Regional Manager' which has always been one of my favourite jokes," he revealed.
Krasinski recently credited The Office with changing his life forever by giving him the opportunity to meet his wife Emily Blunt.
The Office airs Thursdays at 9/8c on NBC.
