Good premise thus far. Always kind of fun to have a reunion type of story. It's short so there's not a lot of depth yet other than just introducing the premise.

On the technical standpoint of writing there are some ways you can improve.

Whenever a new character starts talking, make that a new paragraph. It makes it easier to see who is talking who they're talking to.

Watch your verb tense. You change between past tense and present tense a few times. "5 (Also that should probably be written out 'Five' instead of '5') years after the documentary aired, Kelly sent out a text message..." You're in past tense there.

"'I haven't seen my Dunder Mifflin family in a while!' Pam says..." Present tense there. Change the "says" to "said" and things line up a bit more.

Now admittedly I'm NOT a grammar expert or anything like that. If there are people who are more knowledgeable than me when it comes to grammar issues, please listen to them rather than me.

Still not bad for a start. We all have to start somewhere and the fun thing is that you can only improve as time goes on.
