I have a client using Outlook 2003 on Windows XP. They have a PST for mail from their ISP. Recently moved them from standalone PCs to a windows domain. I setup their Outlook, exported their mail from the old Outlook to their new. Everything is working (reading, replying, etc), however he is unable to delete messages. The delete key does not work, and when he right-click's, delete is grayed out. However, when he selects two messages, the delete key does work and right-click delete works.
