I'm sure that one will be fine too, until one day it's not.
So true.
I've had at least 2 instances in the past 12 years where indoor (CMR) CAT-5e was run outdoors to an Engenius radio and at the other location a Ubiquiti radio and both failed within 5 years. Both were directly exposed full time to the sun and moisture. I actually found water inside the jackets and there were tiny slits in the insulation of one or more pairs...I think this caused some electrical "leakage" between differential pairs (like the orange pair to the green pair) and messed up it's reliable TX/RX and caused errors.
Since I didn't install it I guess it's possible that damage to the jacket was caused by rough handling or poor techniques during the install BUT...... it appears both water ingress points were at sharp bends. I believe the bends stretched the outer PVC pretty thin so it didn't take long for it to develop a slit as the direct sun/night time thermal cycling did a number of it and it opened up, allowing the water in.. Heat up, cool off, suck the water in....rinse and repeat. What I used outdoors (Ubiquiti ToughCable Pro) has such a tough, thick jacket with UV inhibitors I've never had an issue with it and frankly, I've been VERY rough with it.
I have installed a couple of dozen CAT-5e and 6 runs with a CMR jacket outdoors underneath roof eaves and overhangs and tucked under vinyl siding seams where there's no direct sun or rain exposure; most of those are over 15 years of age and are still OK as far as I know, but again.....those are fairly well protected from direct exposure.
