3.5mm (in) to 6.5mm (out) connector not working for input

I have a Focusrite Scarlett 2i2 and those 3.5 mm to 6.5mm adapters as I sometimes use a 3.5mm microphone on my headphones. I can use the adapter fine in the audio output headphone port, but whenever I try to get it to work on the input, the only way that it sounds correct is to have the 3.5mm half way in. I have tried two different adapters and both TRS and TRRS cables. Maybe the Scarlett doesn't accept the adapters? I don't know why it doesn't work. It doesn't matter that much as I don't need it that often, and if I do use it, I result in using the crappy onboard audio of my PC.

If your microphone is part of a computer headset, then it is a "computer microphone" (vs. a wireless belt-pack microphone which has the same kind of plug but is not interchangeable).

Alas, I don't know of any commercial adapters that would do what you are asking for. Frankly, if you can get it to work by plugging it half-way an adapter, then you may have found the only practical solution already. Unless you want to make a custom adapter. But only you can make the trade-off decision whether that is worth it or not.

Considering that most computer headsets are not noted for the quality of their microphones, it might be just as good to plug the headset directly into your computer. You don't really need the Scarlett USB audio interface for headphones/microphone that are designed to plug directly into the computer.

Don't know if I understood the situation.
If it's a computer headset with a microphone and it all connects through a 3.5mm then the microphone pin will be after the ground, closer to the body of the jack connector.
So when you'll plug it, the signal from the mic will go to the ground pin of the 6.5mm jack and obviously to the ground pin of the Scarlett XLR.

To make it work, you should buy a split cable proper for this job, and connect the 3.5mm to 6.5mm adapter to the mic jack:
