Today, I got an e-mail that wasn't in duplicate! My inbox in the hotmail website is not in duplicate: it's just my inbox in OE. I've tried closing OE and then re-opening but the duplicates are still there. Fascinating eh?
Was getting the same, all mail in duplicate using OE6 to read hotmail. Running W98se, think it must be a hotmail to OE problem as Microsoft describe the service as an unsupported Beta. Stopped working completely now.?
