Currently we are hosting our email through POP (Verio). Each outlook client is setup with a pop account and a exchange account. When the user gets mail it goes through (Verio) then is sent to the user mailbox local on their machine lastly the mail gets transferred to exchange. Currently we do not have exchange fully setup as a site. The problem occurs when a user emails a “reply to all” to anyone in the company when the new email is created outlook gets confused and the users name remains in the “to” field (which in outlook is default to remove this). In our active directory 90% of the users are setup as the following “email@example.com”. The remaining users (which are the ones experiencing these issues) addresses have been changed in active directory to firstname.lastname@example.org which seems to put a band aid on this but, is there a fix for this without migrating completely to exchange? Or any third party software you might know to help this fix?
