I've found yet another source that states a drasticaly shorter lifespan for mer than all the other sources. It's an interview (in the Imperial Library it's stated the copyright is from 1999) were Bethesda employees answered questions in a Dunmer's stead. (https://en.uesp.net/wiki/Morrowind:Interview_with_a_Dark_Elf)

There it's stated that while some dunmer can reach age 200 and beyond that it's rare and that in the family of the interviewed mer people don't live beyond 120 or 130 and are considered old by age 100. He explicitely states that this is only true if illness or injury don't take them first.

This information obviously clashes with a lot of dates from Tamrielic history and books.

Basically we are giving wildly differing information about an elf's maximum life span ranging from 120  to 1000 years. It looks like we just have to draw our own conclusions.
