Missing mail attachment option - Zimbra 8.5.1

[jlnmo]

Greetings

We recently discovered that a Zimbra 8.5.1 installation (we have several instances of Zimbra running in our company) is missing the option to attach a message when a user clicks the attach dropdown menu (Zimbra Webclient). The menu shows only "My Computer", "Inline" and "Briefcase". I searched all over the configurations and couldn't find a way to enable the option to attach messages. Is this a bug of some sort or am I forgetting something?

Thanks in advance!

The problem was the lack of the Mail Attacher Zimlet. I was thinking that attaching emails to messages was a default feature. I just needed to deploy the right Zimlet and the problem was gone!
