Dialog templates

Exchange stores dialog templates at

CN=Display-Templates,CN=Addressing,CN=OurMail,CN=Microsoft Exchange, CN=Services,CN=Configuration,DC=company,DC=com

Within Display-Templates, there are nodes for every locale offered. This is the base-16 representation of the locale ID, cf. lcid.txt.

  • CN=409: English (1033/0x409)

Within each locale, there are nodes for different templates.

  • CN=0: User
  • CN=1: Group
  • CN=2: Public Folder
  • CN=3: Mailbox Agent
  • CN=6: Contact
  • CN=200: Search Dialog
  • CN=Exchange: Exchange Send Options

Within each template, there are a number of attributes that may appear of interest. The following four are type-1 ABKT templates:

  • addressEntryDisplayTable: current settings (possibly user-modified; or possibly Exchange default) for the domain
  • addressEntryDisplayTableMSDOS: current settings, tailored for Outlook for DOS (Exchange 5.5), uses row/col addressing instead of pixel units
  • originalDisplayTable: Exchange default for Outlook
  • originalDisplayTableMSDOS: Exchange default for DOS

A fifth attribute exists, but it uses a type-2 ABKT template, which is not documented by MS-OXOABKT. It appears to be a remnant of Exchange 2003.

  • perMsgDialogDisplayTable: Exchange Send Options

Type-2 template

Section titled “Type-2 template”

Type-2 templates have a CNTRL structure of 16 instead of 12 bytes (TRow structure of 40 instead 36 bytes).

struct TRow_v2 {
    uint32_t XPos, DeltaX, YPos, DeltaY, ControlType, ControlFlags;
    struct CNTRL_v2 ControlStructure;
};
struct CNTRL_v2 {
    uint32_t extra2;
    uint32_t dwSize, ulSize, ulString;
};

Possible values for ControlType are given by DTCT_ definitions in mapidefs.h (and/or wabdefs.h). “New” control types — MAPI has known these all along — are: combobox (0x3), dropdown listbox (0x4), radio button (0x9).

CNTRL structure describing a combobox

Section titled “CNTRL structure describing a combobox”
  • gxT2Extra (presumably ulPRTableName). No info. In the only ABKT-2 template ever seen, it specifies a PT_LONG property.
  • dwType (ulPRPropertyName): Property tag of type PT_TSTRING.
  • ulSize (ulNumCharsAllowed): Number of characters allowed to be entered into the edit control.
  • ulString: Offset to a string specifying the regular expression for characters allowed in the edit control.

CNTRL structure describing a dropdown listbox

Section titled “CNTRL structure describing a dropdown listbox”
  • gxT2Extra (ulPRDisplayProperty): Property tag of type PT_TSTRING. This property is one of the columns in the table identified by the ulPRTableName member. The values for this property are displayed in the list. (Unused? Because the values are in ulString…)
  • dwType. No info. In the only ABKT-2 template ever seen, it specifies a PT_LONG property.
  • ulSize. No info. In the only ABKT-2 template ever seen, it specifies a PT_LONG property.
  • ulString: Offset to a string specifying a backslash-separated list of selectable list values.

CNTRL structure describing a radiobutton

Section titled “CNTRL structure describing a radiobutton”
  • gxT2Extra (ulcButtons): Count of buttons in the radio button group. The structures for the other buttons in the group must be contained in successive rows of the display table. Each of these rows must contain the same value for the ulcButtons member.
  • dwType (ulPropTag): Property tag of type PT_LONG. The initial selection in the radio button group is based on the initial value of this property. Each button in the group must have the same ulPropTag.
  • ulSize (lReturnValue): Unique number that identifies the selected button.
  • ulString: Offset to the label text of the control.

Icon association for Exchange objects

Section titled “Icon association for Exchange objects”
Exchange Object Otyp Dtyp DtypEx OL icon OWA
Root container ABCONT unset unset
GAL ABCONT GLOBAL unset
NSPI container ABCONT LOCAL unset

For Otyp, see mapidefs.h:enum mapi_object_type. This tells the object type in C API terms (IABContainer, IMailUser, IDistList, IMAPIFolder, etc.).

For Dtyp, Dtypex, see mapidefs.h:enum display_type.

MSMAPI exposed data

Section titled “MSMAPI exposed data”

The Minimal EntryID expressed by the NSPI protocol makes an appearance in MSMAPI in the PR_INSTANCE_ID property.

The "Contacts" folder itself in private mailboxes:

  • PR_CONTAINER_CLASS=IPM.Contacts

Contact in private "Contacts" folder:

  • PR_OBJECT_TYPE=5 MAPI_MESSAGE
  • PR_MESSAGE_CLASS=IPM.Contact
  • PidLidEmail1AddressType=SMTP/EX

Same contact as seen through the AB provider:

  • PR_ADDRTYPE=SMTP/EX
  • PR_DISPLAY_TYPE=0 DT_MAILUSER
  • PR_OBJECT_TYPE=6 MAPI_MAILUSER

Contact group in private "Contacts" folder:

  • PR_OBJECT_TYPE=5 MAPI_MESSAGE
  • PR_MESSAGE_CLASS=IPM.DistList
  • members in PidLidDistributionListOneOffMembers (PSETID_Address:0x8054:PT_MV_BINARY)
  • members in PidLidDistributionListMembers (PSETID_Address:0x8055:PT_MV_BINARY)
  • entryids found in LIDprop 0x8054 are all muidOOP
  • entryids found in LIDprop 0x8055 can be either muidOOP or WAB_GUID wrapping muidEMSAB

Same contact group as seen through the AB provider:

  • PR_ADDRTYPE=MAPIPDL
  • PR_DISPLAY_TYPE_EX={unset}
  • PR_DISPLAY_TYPE=5 DT_PRIVATE_DISTLIST
  • PR_OBJECT_TYPE=8 MAPI_DISTLIST
