On my Outlook client I am able to open an email, click Actions, Edit Message, then I am able to modify anything from within the email and save the email to keep the changes.

When I do this on my users Outlook client nothing happens when I try to modify the email.

I guess this is one of the limitations of the Online-only version.

Lets say I get one and I dont like the subject I can change it to something of my liking.

Open the email 2.

In Message tab, in the Move group there is an Actions drop-down menu.

Click that and select Edit Message As you can see in the screenshot below both the subject and body have been modified.

I can now save this message and the changes will be saved to the email in my inbox.

You have to open the email in full, I was looking during a preview.

I find folders organize things better or categories, but each person has their own way of finding things.

Is there a way to lock or unlock Office from editing This person is not able to edit emails in Outlook.

However I cant modify the subject if it is pointing down but am still able to modify the body.

I am not able to edit the subject in 2016 while the arrow is pointing down, if yours are down then you put them up it will still work, its only if they are up by default they fail (this is related to showing the To: CC: fields by default, maybe your view is different.
