We are unable to forward Outlook Personal Distribution Lists via email. It looks like Outlook sends it correctly but when it gets to the ZCS it converts the PDL attachment into an email message instead of forwarding as a Outlook Formatted Personal Distribution List. Is this a bug? I did not see a bug related to this on the product portal page for 6.0 (GunsNRoses).
We upgraded to Outlook ZCS 6.0.6 Network Edition recently from 6.0.5. It is running on Ubuntu Server 64-bit. All of the users have upgraded to the new ZOC 6.0.5902.6.
