There is a theory that if you CAN do something, there's no reason why you shouldn't. This is a bad theory, and sometimes can be harmful, especially when you're dealing with QuickBooks.
QuickBooks allows you to delete users. You have a user, you decide to fire said user, you go in to your QB file and it has an option to delete said user. So you select it.
Why wouldn't you?
You wouldn't because it's a bad idea.
You can't delete accounts that have transactions in them, nor can you delete vendors or customers or employees with transactions.
So why should you be able to delete a user? If the user has transactions, and you delete the user, those transactions will have missing links. When we have missing links, we're in an excellent position to end up with data corruption.
The best solution? Just don't do it. Change their password, and leave them there, with all the transaction history linked to that user.
