User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release) Build ID: 20130910160258 Steps to reproduce: In account settings, under copies and folders, I have checked Cc these email addresses and entered my own address in. TB inserts a CC when I create a new email. Until recently it also inserted a CC for any email I was replying to, but now it does not. I think this is a bug. Actual results: TB inserts a CC when I create a new email. No CC to me on replies. Expected results: My email address should have been CC'd on new emails and on replies to emails received.

I have the same problem: I have a Mac running OS 10.8.5. I just updated Thunderbird to v. 24.0.1. In the past I have set Tools: Account Settings: Copies and Folders Cc these email addresses to always cc my own email address. That setting is still shown. However, although it is set as described above, this option does not work - i.e. I never am automatically cc'd on an email that I send. Would someone please fix this?

I have verified that the expected behavior occurs on Fedora 18 x64_64 with TB 17.0.8: Expected results: My email address should have been CC'd on new emails and on replies to emails received.

This is the same as BUG 917231 (https://bugzilla.mozilla.org/show_bug.cgi?id=917231)

Rocketman, thanks for identifying the duplicate. There are two workarounds you can use until the fix lands, described in bug 917231, comment 10 and bug 917231, comment 11.
