Issues with outlook templates

Hi,

I am trying to assist my team in setting up outlook templates, I have managed to do it on one of the mailboxes they use which looks like this - I can find the 'my templates' on this one and set them up with no issues

But there is an odd old mailbox we have which looks like this and does not seem to have the templates option available, anyone know how to do this? the inbox and email look like this

any thoughts?
