Default "Prevent copying" delivery option in 8.5 client

After installation of new 8.5 beta2 client on my Windows XP computer I have one of Delivery Options “Prevent copying” checked by default. So I need to uncheck this option every time I create new message.How to change this default setting?

I use the same mailbox with 6.5 design on the same Domino 6.5 server as before the new client installation. In old 6.5 client this option was unchecked by default. I think it means this setting is somewhere inside client configuration and it is not associated with mailbox design.

Dear colleagues, please advise …

I have not try 8.5 yet, but in 8.0.2, you could always set it under Preferences-> Mail.

Thanks for advice, but I can’t find this option in Preferences-Mail. I can see “Encrypt…”, “Sign…”, but not “Prevent copying” or “Return receipt” or “Auto spellcheck”. These default options should be somewhere else…

Where? Can anybody help?
