Outlook 2016 Outlook - cannot save subject line changes

I believe this is out Outlook 2016. I am working off of a server and don't see where the 'about' is but it looks like what I have @ home.

I always open an email, change the subject line, hit X and then save the email.
Now when I hit X the email closes w/the original subject line.

I have almost no rights on this machine..what can I do?
