If you want to be sure about the actual aircraft... Just check the Mel -> xfer valves fault (or failed) in open position .... If the dispatch is granted you have the official answer
(which is YES you can
)
Outer tank high temp may be triggered On a very hot day... But if you look "through" the procedure(fuel l (r) outer tank high temp) the real problem exists while the outer tank is full and your temp is high ... The procedure is to disconnect the idg or to increase your fuel flow to try to cool down your idg and this applies at temps 65 or 57 degrees while the auto ignition temp Is around 210 degrees .... So the real concern is rather your idg overheat I think
your ecam advisory MSG is triggered for fuel temp higher than 45 or 55 degrees and the recommended action is to switch your galley power off (reduce your idg loads )
