I think this has more to do with whether the recipient notices that they have a PM and looks at it. PMs will stay in the "outbox" until the recipient reads it. So if it's still in the outbox, the recipient either has not been online to read their PMs, or simply has not noticed that they have a PM waiting.
At least, that's how it worked when I managed a phpBB.
