It's hard to say, especially with conflicting information.

According to the Elder Scrolls Online website, 200-400 is a rough estimate of the average elven lifetime. There is only one example of this that I know of, and that's Neloth's mycologist. Her dialogue implies that she's roughly 200 years old, and as I recall she calls herself old.

On the other hand, there are many examples of older elves. I find it difficult to believe that Symmachus and Barenziah would be able to have kids when they're both around 400 if 400 is "really old." I also find it interesting that Brand-Shei in Riften has black hair even though he'd be close to 200 years old.

I'd say that AngryEnclaveSoldier's estimate is probably the best guess at average ages. But remember that any life (especially for an elf) can be drastically lengthened with various types of magic.
