Hi,
I have the same issue but I do not have a separate "old outlook" app since it is part of the Microsoft Office app. And I cannot afford uninstalling Office as I would lose Excel, ppt and Word.

Thank you for you help on that matter.

There is no "Change" option with Office 365.

For my case, there is a "Change" option if we look at "Office 365" in the control panel (instead of "Settings")

Nevertheless, the "Change" just triggers a "repair" of the app, which is not what we want here.

This doesn't work for the Outlook that comes with Office 2021 Digital purchase. I'm using the NEW Outlook and would like to uninstall the Old Outlook Office component to recoup the disk space. Apparently, Microsoft did not take this option into account when it started messing around with everybody's systems! It arbitrarily decided to leave its garbage laying around on my HDD taking up space.
