Email not adding to call details

[Dan Munns]

Hi all, 

Before I raise this as an issue with support, I have noticed that some emails do not log the subject / email body as the summary / description.

I raise the request and the info shows up fine. Some of my service desk guys log request and the fields are blank. 

It looks almost like a permissions issue, but this used to work and I have made no changes to email settings or user permissions. 

Any ideas?
