GMs, how would you handle a troll moving through a 5-foot dungeon corridor during combat? Obviously the troll got in the room through the corridor. If you want more details I can provide spoilers by mentioning the P2e adventure, but I am surprised not to see this question not mentioned by a previous beginner GM like me.

I agree. A large creature in a 5-foot wide space most likely treats it as difficult terrain.
As a rule of thumb, I'd recommend using Squeeze for anything smaller than one's shoulders, but larger than one's head.

What are the exact rules for oversized creatures in small rooms or hallways?
There aren't any. At least I and some other guys here couldn't find them.
"One size smaller passage counts as a difficult terrain" is kind of a homerule. Which is rather widespread though. We play it like that for example.

Is it though? Sample DC rules list the following:
Trained space barely fitting your shoulders
Master space barely fitting your head
If it's much wider than your shoulders, then it's not squeezing. If it's not squeezing and it's not normal movement, then logically, it's probably difficult terrain.
Large creatures in 5 foot corridors fall in that logical space.

The point Deriven made is the Exploration trait. Which means An activity with this trait takes more than a turn to use, and can usually be used only during exploration mode.
This takes the Squeeze action, on which all of this depends, out of encounter mode.The reason everyone ignores this is there are just no other guidelines or rules at all. So we use what we have, even though it is explicitly inappropriate. It is our only point of reference.
It is just another rules gap. It technically is GM territory.
If you mean that the sample Squeeze DC gives you a boundary line between merely difficult terrain and requiring the Squeeze action. OK.
So if you are Trained in Acrobatics gaps larger than your sholders don't require a check??? I'm not sure what that is what it says. It leaves a lot of things unknown. But it is probably a fair ruling.
In this case a Troll is described as 12- 15 ft high. I visually judge from its picture that it is 7+ft accross the shoulders. So the gap is narrower than its shoulders. A troll is not typically proficient in Acrobatics as listed. Therefore it needs to use the Squeeze action to get out, which means it is an Exploration action and therefore takes 10 minutes approximately to get out, maybe one minute on a good roll. No doubt the PCs will want to exploit this if they realise it.

Admittedly, under the Squeeze rules in a line telling you when not to use the Squeeze rules is maybe not the best place, but:
"You contort yourself to squeeze through a space so small you can barely fit through. This action is for exceptionally small spaces; many tight spaces are difficult terrain that you can move through more quickly and without a check."
I don't think many groups count normal-sized doorways as difficult terrain, but they're definitely smaller than your space.

On reflection I think that the timings given in the Squeeze Action and in the Quick Squeeze Feat should reasonably count as a case of specific overriding general.
The general being the ten minutes associated with the Exploration Trait
The specific being the number of actions or rounds given depending on the success state of your acrobatic check to squeeze.
The Exploration trait is really there as a warning that this is typically a long running activity. The actual time may be less depending on skill.
Putting what Ravingdork is saying together, my interpretation would be:
If you are Untrained in Acrobatics in a space that is less than the number of squares required for your size, up to the space that doesn't easily fit your shoulders. It is just difficult terrain.
Trained in Acrobatics the dividing line is for a space barely fitting your shoulders.
Master or Legendary in Acrobatics it is for a space barely fitting your head.
A Squeeze check is required if the space is tighter than this.

I don't personally believe you can ignore having to Squeeze if you're a Master in Acrobatics and attempting to work through a space barely large enough to fit your shoulders. That just sets the DC of the check you'd still have to make (and probably succeed). Nevertheless, I believe the implication is that a space just big enough to fit your shoulders is the dividing line between something being difficult terrain and Squeezing.

My take:
Squeeze:
You contort yourself to squeeze through a space so small you can barely fit through. This action is for exceptionally small spaces; many tight spaces are difficult terrain that you can move through more quickly and without a check.
(..)
Sample Squeeze Tasks
Trained space barely fitting your shoulders
Master space barely fitting your head
If I as a normal human tried to walk through a corridor about 1.5 feet (or 45cm) wide, it would be narrower than the width of my shoulders (let's call my shoulders two feet wide). I could easily walk down the corridor, but maybe not at full speed, since I would have to walk a bit sideways. In other words - difficult terrain; half speed. A corridor that is tall enough, but just a bit narrow - that's merely difficult terrain. (In a previous job there was an gap between two pillars less than a foot wide, that I regularly used as a shortcut, even though I'm 6" tall.)
Trolls can move sideways too!Now if I instead as a normal human tried to get through a tunnel that was only 1.5 feet wide and 1.5 feet tall, then I would have to squeeze. Or for that matter a tunnel 2 feet wide and 2 feet tall. That would be bothersome, and I'd probably have to roll for Acrobatics in a squeeze check.
There's quite a bit of difference between an opening (or hallway) that is small, vs one that is merely narrow. As a biped I can easily get through tall but narrow corridor, while I would move very slowly through a corridor that was wide, but low.
So - I would definitely rule that a Troll could walk down a 5ft wide (but tall) corridor just fine - that it was merely difficult terrain.
And hey - if this was the lair of the troll, where the troll had lived for a long time, and walked up and down that corridor on a regular basis, I might even rule that it could move at full speed.

Thank you everyone for this excellent and well-reasoned discussion/debate. I appreciate everyone taking the time to explain their thoughts. The different perspectives really help. Based on what I have learned, the height of the dungeon ceilings, and the fact that the troll lives in a room with five-foot corridor exits, I have decided to go with difficult terrain.
