Hi Ann,

" Under Share the Send by email is grey ie not in bold as usual, but the formats - Word etc are in bold and when clicked on an email (new message) comes up but if I've clicked on Word the document appears to not have been changed from Pages. Hence the attachment has been blocked by the recipents Outlook Express."
When you 'share' a document, you need to choose a format in which to share it. For reasons unknown, Apple has decided to change the layout of the Share menu to make "Send via Mail" and "Export" non-selectable category headers, and place the format choices in the top-level menu. It's a design choice, but one I can't see much benefit in.
Your document itself will not show any change in format if you choose "Word," but if you check the attachment to the email message produced, you see the .doc extension indicating it is a Word file. If you have Word (or one of the open source Office applications (eg. LibreOffice, OpenOffice.org), 'Sharing' a Word copy of the document with yourself, thenopening it with one of these applications (but not with Pages). All will open a Word format document, and none of them will open a Pages format document. Your resut should tell you whether the conversion has been made.
