When searching for a past sent email in a customers communication tab I discovered that only their past 21 emails had saved. I looked into it more and every other long standing customer I saw had exactly 21 emails saved, and no more. This is problematic for us as we use our email history to store important context between us and our customers, and for many of them it doesn't even show the entirety of 2026. Can these be recovered, or is there a way to expand the cache of emails we can store and view? the chat bot says no.
