On a pressurized plane perhaps there may be one door which can be maximally
sealed only from the inside, and it certainly is reasonble to think that
door might therefore leak when the airplane is left in the rain.

But how can windows or other doors leak with a pressurized airplane? If it
is nearly airtight then surely it ought to be perfectly watertight.

Inflatable door seals.

The cabin door and emergency exit windows had inflatable seals that inflated
only when the engines were running. With the aircraft parked and the seals
relaxed rain water could come in. The operator swore by the taping method when
parked outdoors.

Bingo. I have this issue on my 340. If the emergency window is too
tight the seals get squashed and won't seal for pressurization, but if
they aren't too tight then it'll leak a bit when not pressurized.
Haven't yet found the best solution other than don't park in the
rain...
