Hi, I'm getting [!! SPAM] in the subject line of my emails and I'm wondering how I can get rid of this. Also, at times when I want to send an email, the "New" option becomes greyed making it impossible to send emails. I have run the "Detect and Repair" option but to no avail. What can I do?

The spam tag is probably added by your intelligent message filter, or other spam filtering product. It would be removed there. also, see if this helps for your new button issue: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=597493&SiteID=17
