Depends on how long you believe elves in TES live for. The only time it's ever stated directly, it claims they live on average for 200 years or for around 300 with powerful magics. It'd also depend on how old he is in Morrowind to begin with. But, elves aren't immortal, so we know he'll die eventually.
