if we update account type, would it be possible to output past access log ?

Hi there, 

Welcome to the Box Community, I'm happy to help!

Please be advised that Box reports are NOT retroactive. If you were to upgrade an account that did not have reports at the time of the incident (Personal or Starter accounts), reports would begin tracking actions on the day you upgraded. This means you will not be able to run a report for actions/dates prior to the upgrade.

Thanks for reaching out and let us know how else we can help!

Noted with thanks.

Again, thanks for posting in the community and feel free to post again if you have other question.
