MS office MAC 2011, unable to use edit functions to copy emails to then use as attachments

I have previously used MS office for windows for many years, but have recently switched to MAC

With MS office for Mac 2011 i am unable copy any email so that i can then attach them to another email that i wish to send.

There is a function that allows forwarding an email as an attachment but this is not what i need.

If i right click to see local dialogue functions "copy" is not included, so i then go to Edit on the top toolbar, and there all the functions, Cut, Copy Paste. ect are not available either, becuase these options are in shadow not in bold.

I have also tried to down-load the MS office for MAC 2011 service pack 3 upgrade, just in case this would help, but after downloading the file my MAC tells me that Office 2011 is not installed on my MAC hard disk (which it definitely is)

Any idea's as to where my problem my lie please.

Thanks in advance for any help.
