Agree with MK - we should have an option to enable or disable internal comment in Jira at project level.

Comments made internally in Jira do not show in JSM which renders the View issue link in emails useless as "internal" comments are hidden. For our Internal IT project we want everything visible in both Jira and JSM - so long as the Comment Internally button is there it's not an option. 

We should have an option to enable or disable internal comment in Jira Service Desk at project level. Some project might use internal comment option some may not use it. Hence, we need this configurable at project level.

any update on removing this "Share with" option? 

You can just add to the "Announcement Banner"
<style>button.aui-button.aui-button-primary.sd-external-submit

</style>

Its not perfect as in some scenarios it doesn't get loaded until you refresh the page - but these seem to be edge cases and so it works pretty well; good enough for our usage anyway. I also had to be able to do it only for a certain project, so I extended it with some JavaScript to allow that.

And this way it doesn't need to be installed on individual browsers as in a chrome-add on. Of course all of these are just hacks - ideally JIRA should have config options for this - but until then.

added to the end of the "Announcement Banner"
<script>
const thisWindowURL = window.location.href
if(thisWindowURL.indexOf("xxprojectkeyxx") >= 0)

{ document.write("<style>button.aui-button.aui-button-primary.sd-external-submit

</style>");
}
</script>

_Edit: the document.write line should all be one line to the end of </style"); but this editor keeps breaking that.

Sure... here you go!

If you look at line 21 of manifest.json you can see where it uses wild card notation to only work for the cloud instance of Jira (atlassian.net), if you check out the code, and modify that line to match the URL of your self hosted server instance of Jira, and then add it to Chrome as an unpacked extension, it works, I've tested it.

@Joseph Rowe Can you post the link to the thread?  I would like to check out the chrome extension

@stephane, I was able to remove it myself using a google chrome extension that some guy posted in another thread.  His works for the cloud version of Jira, but you can check out his code from Github and it's a 1 line fix to make it work for the server version of jira.  Not the most elegant solution as it would have to be applied to every computers browser that uses Jira, but it works.

I dont understand how this can't be disabled.....annoying ...i spent 3 hours to try to find how to do it.....

Please move on to the new age, We have been on the moon 50 years ago.....! 

We really need this feature.  Same thing for attachments.  There really should be the ability to remove the "Share with Customer" button when adding attachments.

In my company customers service answer to issues. Sometimes there need information from specialists. We don't want spécialists can write directly to customer. Customers service take notice information provide by specialist and draw up answer to customer. it's his responsibility in the running of our business. And we don't want a problem because specialist deceice himself with comment button.

I think this is great to configure button "share with customer" for role in the project
