menu items are greyed out

I’ve set internet email as /Applications/Mail.app/ but the menu items are all greyed out exept to create master or HTML documents. My email client is IMAPI. I’m using a Macbook Pro.

And what does it have to do with LibreOffice?

I don’t know how to revise my original question after having logged out so I have to add a little to explain. Libre Office has (supposed to have) an option to send the document as an email attachment. File, Send, E-Mail Document. The menu items I refer to are under the Send Menu. I gathered those who could actually answer the question would have either had the same problem and solved it or knew the menu options and what setup was needed prior to expecting it to work. I suppose I should have expanded my question to cater for everyone who read it. Sorry.
