Hi. Thank you for your question and reaching out.
Regardless of the state of the use license, a document cannot be accessed after it has expired (cached or not).
End use licenses are cached by default, and I think they stay cached for a year.
If you choose to restrict the end use license's cache time, you have two choices: 1) let end use licenses be cached for a set number of days between 1 and 365; or 2) don't cache end use licenses, which implies that the use license expires as soon as the Office document is closed.
