When connecting to a POP inbox, I keep getting a "pop lock busy! Is another session active?" message. What's wrong?
John Zukowski POP only supports having one reader/writer to the mailbox. If another mail program is reading from the mailbox, you might get this error. Another cause of the error is if your program ran, threw an exception, and didn't properly close the mailbox. In the former case, you'll need to make sure you're not trying to read from multiple places. In the latter case, you'll need to wait for the session to timeout.
