Greyed out options within Outlook 2013

Various options on my Insert Tab and Format Text tabs within my Outlook new message are greyed out.

Not all options, just: Table, SmartArt, Chart, Screenshot, TextBox, WordArt, Equation & Drop Cap in "Insert Tab", and Styles within "Format Text" tab.

1. It is not because I am in the To or CC field. I am in the main email field. Similarly, I have HTML as the Format, and have tried Rich & Plain  this is not the problem.
   
2. I am running Outlook, Access, Lync, Infopath, Project & Publisher 2013, but Word, PP, Excel etc. 2010.
   
3. I have disabled Add-ins and also run in Safe Mode. This does not change anything.

Any idea how to get this working? I'm getting myself very puzzled...
