Suppose a person obtains a volume license while working for a company (perhaps paying for it), then leaves the company.
Do do they continue to have the right to run the software?
Does it depend on actions or permission from the company?
How would this user, without media, reinstall their license later?
This is in order to answer similar questions in other forums. I am not on this position and so cannot provide more details!
If the company owns the license they get to dictate who can and cannot use it.
That is different, then, from Microsoft who insist that volume license is for employees and therefore cannot leave the company, even if the employee paid for home use.
