I have an exchange server and fax server setup. The Fax server is sending mails to users of this exchange server. While sending the mails, the fax server is setting one MAPI property named PR_CREATOR_NAME. When outlook reads the mail form the server, the property is not visible.
Probably the exchange server is not allowing to set those properties.
I have checked the fax server.There is no problem with it.
Can you please provide some help regarding this.
