How do I show duplicate email in Mail 6.0 (Mac OS X 10.8)

Under Mail in Lion, there was a link in the top right corner when I had duplicate email.


Under Mountain Lion, that information is no longer there.


This is a problem for me as I archive email for auditing purposes... Finder will not allow me to drag/copy an email that has a duplicate to a Finder window leaving me unable to copy this email.


Thoughts? Experiences?

Same for me - I can't see duplicates


I have copies of a special email with attachment I use as a workaround to delete sent attachments, but in the mountain Lion upgrade I have lost the ability to show multiple copies so I can delete just one and keep the others for later tricks.


There is also a bug which prevents me deleting attachments from sent emails, which is why I need the multiple copies of the email with the blank attachment

Found a solution in another thread. Works perfectly.


To disable automatic grouping of duplicate messages, quit Mail then run this command in Terminal:


defaults write com.apple.mail AlwaysShowDuplicates -bool true


To revert to the default setting, run this command:


defaults write com.apple.mail AlwaysShowDuplicates -bool false


or simply delete the setting altogether with this command:


defaults delete com.apple.mail AlwaysShowDuplicates


If you want to see how Mail behaves with this setting enabled, but without modifying your preference file, start Mail from Terminal with this command:


/Applications/Mail.app/Contents/MacOS/Mail -AlwaysShowDuplicates YES

Thank you! Just upgraded from Lion and when testing a mailing script after a server upgrade I thought the script wasn't working because I was not receiving the duplicate test emails. I couldn't find the place in Mac Mail to show all of the duplicates so I thought they weren't there. I was not looking forward to debugging the mailing script to see why it wasn't sending - so relieved to see that the emails were there and just hidden. The Terminal command did the trick.
