Comments: | By: Graham Barnett (GrahamJB) 2015-02-13 06:43:52.803-0600 For reference on this jira I had to set this in Exchange (seperate to code fix): {noformat} Set-TransportConfig -HeaderPromotionModeSetting MayCreate {noformat} With Exchange Server 2007 SP1 RU8 we disabled promotion of custom X-Headers to named properties when mail was submitted anonymously via SMTP. Only authenticated connections would work. With Exchange Server 2007 SP1 RU9 we disabled all named property promotion on messages submitted via SMTP, however Exchange Server 2007 SP2 introduced a new feature on the global TransportConfig object called HeaderPromotionModeSetting. *Impact* So what's the point of all this? Named properties are used for many thing, but a big impact for many is the use of named properties where POP and IMAP clients are concerned. Because Exchange Server 2007 does not keep the Mime for a message around, nor does it keep a full Mime Structure of the originally submitted messages, we will reconstruct the headers of a message when going through item (MAPI) to MIME conversion, IOW, when downloading a message via POP or IMAP. If the X-Header on a message has never been promoted to a named property then it will not show up when RETRieving or FETCHing the message via POP or IMAP. Because the named property table is managed on a per database basis, once a named property has been promoted into a specific database it will always be provided to the POP/IMAP client.
