My first full-time job had an unexplained email expiry policy. After being frustrated several times at losing some explanation on how/why, I started forwarding all my emails to gmail. In retrospect, that's probably a worse result to whoever imposed the expiration.
Fortunately, these days people are better about consolidating knowledge on wikis or some kind of shared docs instead of only email.
The excuse of resource contention provides plausible deniability
But nobody ever talks about it (except on said un-recorded meetings. That reminds me, I should explain this to our junior today, so that he knows for the future).
(apologies it's on medium, I couldn't find it anywhere else)

iirc at the time the only industries that required retention were health, legal and government
With SOX (PCI, FDIC, et al) retention laws we had another explosion of work rolling out all the compliance features of Exchange
Those were crazy times getting everybody either migrated with email or onto corporate email - there's a similar explosion of work right now with migration to M365
The IT people get smart about looking for OST or PST files, but let's see them catch that :-)

Then configure a new mail account in Outlook and connect to the IMAP server. It's optional, but convenient for replies, to configure the account to send via postfix if you have an internal SMTP server to connect to.
I gave up on email folders years ago, so at the end of the month would just create two new folders in the archive account (YYYYMM and YYYYMM_Sent) and drag all the mail from the Exchange account into the IMAP folders. Et voila! You now have your own local email archive.
Imagine getting sued and having the entire paper trail in your email going back 3+ years. I expire all email after 1 year.
The reason being that it's hard to show intent to defraud, and much easier to threaten bad press.
Email hosts love 50/100gb/unlimited mailboxes because nobody wants to migrate a bunch of giant mailboxes
A bit like when investigating police/government misconduct and a lot of files turn out to have been destroyed - but of course our data gets kept forever
