Unwanted Multi Deliveries using Microsoft Outlook

On a couple of occassions recently, I have sent an e-mail with attachment to a number of addressees using a group address. They report back that the same message has been received with duplications (10 times at one report!).
Is this caused by a virus or does my Options need looking at?
Using Windows XP Pro. The attachments were .pdf files.
Any ideas please?
