Thanks Mike,

I'm on my own admin profile and cannot get the Personalise Activities to show.   When I right click I only get the Web Browsers Right Click Menu (Back / Forward / Reload etc).

It does have a small >> to expand out some filters

Which when expanded look like this

Apologies if i wasn't clear in my initial post but other user groups who work with the tasks can see the Work Notes and Additional Comments fine (They use ITIL Role).

These appear below the Additional Comments Field :-

It's Just our 3rd Party without the ITIL role who can't see them.   I'm hoping there's a way to let them see without the ITIL Role.  

Hope this clarifies and I really Appreciate the help so far.

Thanks

Paul
