I use a desktop machine and it is been working with Windows XP. The issue is basically with my Hotmail account. I think someone is using my hotmail account and sending mails. I do not know what could have been causing the same. Please suggest me what could have been the reason for the same. I need the support for the same so that I can work well. Hope to get the desired solution which will be helpful and can make the things to get sort as required.
