Through an unfortunate turn of events, I ended up with 160,000 useless messages in my MS Exchange inbox. They're not in a folder, rather in the root of the inbox itself. I desperately need to delete them all, even if I have to delete my entire inbox. I'm desperate because I need to hook up my BIS BlackBerry to the IMAP service in order to get push e-mail on my handheld, which is absolutely critical at the moment.
Thus, the question: How do I either (a) delete the useless messages; or (b) delete everything in my inbox if (a) were impossible? Note that I don't have access to Outlook as I'm a Linux user in a Microsoft company. The POP3 service is disabled and I don't think I could get enough traction to have it enabled. Thus this leaves me only with options involving IMAP. This also means that the (hypothetical) tool(s) that I'm looking for need not be Exchange-specific.
TIA.
EDIT: I didn't have my glasses on at the time. The number is one-hundred and sixty thousand. Not sixteen thousand as previously thought.
