I cannot access my junk mail folder. Its locked or somehting - yet i see some unread messages there - it wont open or let me access to it.. I dont know what happened.
What kind of email account do you have? If it's IMAP and you have selected to store junk messages on server, you won't be able to access the folder when you're not connected to the internet. The message list you see is probably a local cache.
