Just in case anyone is reading this it has just got weirder! Having added another email account to my outlook my Outlook 2010 I now find that, when I select a message in the new account's Inbox the Delete X is not greyed out but the first account's still is. I have tried all the settings I can find, both for the Outlook Accounts and the Data Files, but to no avail; they seem the same in both accounts. If anyone reading this has even an inkling of what I am doing wrong please post. Thanks
