Not true.
It’s much easier to keep old data in active storage where it can be classified, searched, and have retention/deletion policies applied. Moving it elsewhere makes it more likely you’ll just hang onto it forever while not using it at all.
When was the last time you had to find a 20 year old email? Share your anecdotes.
Edit: I’m not being snarky, there are legitimate and more functional solutions.
Warranty… Some are 15-20 years, but you need proof of purchase docs, which are often emailed data.
Why not having an archive of exclusively warranties? Emails can be downloaded, indexed and compressed. I agree on keeping archives of old stuff. But emails used as cloud drives are a huge problem for IT and security reasons. A legal folder is better and facilitates backup, encryption and much more accessibility.
So you don’t really want to archive in the technical sense, you want it offline for security, which is valid but extremely inconvenient for regular end users.

I don’t disagree that you should set up retention policies to delete old email, I disagree that you should remove old emails from primary service/storage.
I actually did need a 15 year old email a few months ago. I don’t recall what I needed, but I then set up a retention policy to delete old stuff.
