Hi All, Sorry to reply to my own message yet again, but with pointer from someone in a telephone conversation today, followed by some googling, I've come up with a solution to my problem. For anyone who gets into the same situation I suggest you take a look at the following link. http://www.msoutlook.info/question/141 I would also suggest however, that it looks as if the solution only works if you have Outlook 2003 or higher, and the solution is different depending whether you have Outlook 2003 or 2007. ** To leave the list, click on the immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=unsubscribe] ** If this link doesn't work then send a message to: ** access-uk-request@xxxxxxxxxxxxx ** and in the Subject line type ** unsubscribe ** For other list commands such as vacation mode, click on the ** immediately-following link:- ** [mailto:access-uk-request@xxxxxxxxxxxxx?subject=faq] ** or send a message, to ** access-uk-request@xxxxxxxxxxxxx with the Subject:- faq
