MAPI constants

Applies to: Outlook

This topic contains constant definitions, MAPI interface declarations, and class and interface identifiers used by the MAPI APIs.

Class and interface identifiers

Use the DEFINE_GUID macro defined in the Microsoft Windows Software Development Kit (SDK) header file guiddef.h to associate globally unique identifier (GUID) symbolic names with their values, unless otherwise indicated.

Attachment security conversion API

This section contains constant definitions and interface identifiers for the Attachment Security API.

// {b2533636-c3f3-416f-bf04-aefe41abaae2}

Use the MAPIMETHOD macro defined in the Windows SDK header file mapidefs.h to define the pure virtual function IsAttachmentBlocked.

#define MAPI_IATTACHMENTSECURITY_METHODS(IPURE)         MAPIMETHOD(IsAttachmentBlocked)         (LPCWSTR pwszFileName, BOOL *pfBlocked) IPURE;

Use the DECLARE_MAPI_INTERFACE_ macro defined in the Windows SDK header file mapidefs.h to define the virtual method table for IAttachmentSecurity.

DECLARE_MAPI_INTERFACE_(IAttachmentSecurity, IUnknown) 
{ 
    BEGIN_INTERFACE 
    MAPI_IUNKNOWN_METHODS(PURE) 
    MAPI_IATTACHMENTSECURITY_METHODS(PURE)

MAPI store

This section contains constant definitions and interface identifiers used by APIs that interface with a MAPI store.

Constants

fnevIndexing
((ULONG) 0x00010000)
A store provider can specify fnevIndexing in the ulEventType member of the NOTIFICATION structure to notify the indexer that an object is ready for indexing. The info member of the NOTIFICATION structure contains an EXTENDED_NOTIFICATION structure.
FS_NONE
0x00
A client can call IFolderSupport::GetSupportMask and check for the returned bitmask. FS_NONE indicates that the folder does not support sharing.
FS_SUPPORTS_SHARING
0x01
A client can call IFolderSupport::GetSupportMask and check for the returned bitmask. FS_SUPPORTS_SHARING indicates that the folder supports sharing.
INDEXING_SEARCH_OWNER
((ULONG) 0x00000001)
Identifies the process that is pushing a notification to an indexer that an object is ready for indexing.
MNID_ID
As defined in the Microsoft Windows Software Development Kit (SDK) header file mapidefs.h
A value for the ulKind field of the MAPINAMEID structure.
MNID_STRING
As defined in the Microsoft Windows Software Development Kit (SDK) header file mapidefs.h.
A value for the ulKind field of the MAPINAMEID structure.
MSCAP_RES_ANNOTATION
((ULONG) 0x00000001)
If a client specifies MSCAP_SEL_RESTRICTION in mscapSelector for IMSCapabilities::GetCapabilities, GetCapabilities can return this value if the store ignores invalid parameters in a restriction.
MSCAP_SECURE_FOLDER_HOMEPAGES
((ULONG) 0x00000020)
If a client specifies MSCAP_SEL_FOLDER in mscapSelector for IMSCapabilities::GetCapabilities, GetCapabilities can return this value if the store is a non-default store that supports folder home pages.
STORE_PUSHER_OK
((ULONG) 0x00800000)
A client can get the property PR_SUPPORT_MASK to determine the characteristic of a message store. If the store provider sets the STORE_PUSHER_OK flag in the bitmask, that means the MAPI Protocol Handler will not crawl the store, and the store is responsible to push any changes through notifications to the indexer to have messages indexed.

Definitions for namespaces

The following globally unique identifiers (GUIDs) represent the namespaces of named properties. They are indexed by the MAPI Protocol Handler (PH), and are documented as read-only.

Caution

The named properties should not be used to create or modify items.

Additional MAPI constants

This section contains constant definitions including error codes, and interface identifiers used by MAPI APIs that were not previously exposed and documented.

DIALOG_MODAL
((ULONG) 0x00000001)
When a client calls the IAddrBook::Details method, the client must set the DIALOG_MODAL flag in the ulFlags parameter to display the modal dialog box showing the details about a particular address book entry. This constant is defined in mapidefs.h.
ITEMPROC_FORCE
0x00000800
In Outlook 2007, wrapped PST stores have rules and spam filtering processed on new messages before MAPI clients are notified of the new messages. A provider or client using the IMAPIFolder::CreateMessage method to create a new message in PST stores should set the ITEMPROC_FORCE flag in the ulFlags parameter of the IMAPIProp::SaveChanges method to indicate to the PST store that the message is eligible for rules processing before the store notifies any listening client of the arrival of the new message. Note that such rules processing only applies to new messages created on a server that is not a Microsoft Exchange Server, because Exchange Server processes rules for messages on the server. Hence the provider or client creating the message must pass this flag in combination with NON_EMS_XP_SAVE, which indicates the server is not an Exchange server.
MAPI_BG_SESSION
0x00200000
A client can call the MAPILogonEx function, setting the MAPI_BG_SESSION flag in the flFlags parameter to log on to a session and carry out any operations in the background. In general, if a client intends to do processing on a background thread or in a separate process in a manner that is unobtrusive to the foreground thread, it should call MAPILogonEx with the MAPI_BG_SESSION flag. An example where this is used is a client application, such as an indexing engine, opening a Personal Folders File (PST) for background type access.
MAPI_CACHE_ONLY
0x00004000
A client can call the IAddrBook::OpenEntry method, setting the MAPI_CACHE_ONLY flag in the ulFlags parameter to open an address book entry and to access it subsequently only from the cache. An example where this is used is a client application that wants to open the Global Address List in Cached Exchange mode and access an entry in that Address Book from the cache without creating traffic between the client and the server.
MAPI_DIALOG_MODELESS
0x0000000C
This value can be passed to the Simple MAPI MAPISendMail function in the ulFlags parameter to specify that a modeless dialog box is displayed by the default mail application. If neither this flag nor MAPI_DIALOG (0x00000008) is set, no dialog box is displayed.
MAPI_NO_CACHE
0x00000200
If Microsoft Office Outlook is in Cached Exchange Mode and a store has been opened in cached mode, a client or service provider can call IMsgStore::OpenEntry, setting the MAPI_NO_CACHE flag in the ulFlags parameter to open an item or a folder on the remote store. Note that if you open the message store with the MDB_ONLINE flag on the remote server, you do not have to use the MAPI_NO_CACHE flag.
MAPI_UNICODE
0x80000000
A client or service provider can call the OpenIMsgOnIStg function, setting the MAPI_UNICODE flag in the ulFlags parameter to create Unicode .msg files. The resulting IMessage : IMAPIProp file shows STORE_UNICODE_OK in its PidTagStoreSupportMask Canonical Property and supports Unicode properties. This constant is defined in mapidefs.h.
MDB_ONLINE
0x00000100
If Outlook is in Cached Exchange Mode, a client or service provider can call the IMAPISession::OpenMsgStore method, setting the MDB_ONLINE flag in the ulFlags parameter to override the connection to the local message store and open the store on the remote server. Note that you cannot open an Exchange store in cached mode and in non-cached mode at the same time in the same MAPI session. If you have already opened the cached message store, you must either close the store before you open it with this flag, or open a new MAPI session where you can open the Exchange store on the remote server by using this flag.
NON_EMS_XP_SAVE
0x00001000
A client can call the IMAPIProp::SaveChanges method, setting the NON_EMS_XP_SAVE flag in the ulFlags parameter to indicate that the message has not been delivered from an Exchange server. This flag should be used in combination with the ITEMPROC_FORCE flag in the ulFlags parameter to indicate to a PST store that the message is eligible for rules processing before the PST store notifies any listening client of the arrival of the message. This rules processing only applies to new messages that are created with IMAPIFolder::CreateMessage on a server that is not an Exchange server (in which case the Exchange server would have already processed rules on the message).
SPAMFILTER_ONSAVE
0x00000080
A client can call IMAPIProp::SaveChanges, setting the SPAMFILTER_ONSAVE flag in the ulFlags parameter to enable spam filtering on a message that is being saved. Spam filtering support is available only if the sender's email address type is Simple Mail Transfer Protocol (SMTP), and the message is being saved to a store for a Personal Folders file (PST).
STORE_ITEMPROC
0x00200000
If this flag is set in the PidTagStoreSupportMask Canonical Property of a wrapped PST store, it indicates that when a new message arrives at the store, the store has rules and spam filtering processed on the message separately. The store then calls IMAPISupport::Notify, setting fnevNewMail in the NOTIFICATION structure that is passed as a parameter, and passing the details of the new message to a listening client. Subsequently, when the listening client receives the notification, it does not process rules on the message.
STORE_UNICODE_OK
0x00040000
If this flag is included in the PidTagStoreSupportMask Canonical Property, it indicates that the store supports Unicode storage. A client can look for the presence of the flag to decide whether to request or to save Unicode information to the store.

Definitions for archiving items in a folder

The following constant definitions are values used to set the PidTagAgingGranularity Canonical Property.

#define AG_MONTHS 0 
#define AG_WEEKS  1 
#define AG_DAYS   2 

Definitions for displaying remote objects

The following constant and macro definitions are for displaying remote objects. For more information, see the PidTagDisplayTypeEx Canonical Property.

#define DTE_FLAG_REMOTE_VALID0x80000000 
#define DTE_FLAG_ACL_CAPABLE    0x40000000 
#define DTE_MASK_REMOTE        0x0000ff00 
#define DTE_MASK_LOCAL        0x000000ff 
  
#define DTE_IS_REMOTE_VALID(v)(!!((v) & DTE_FLAG_REMOTE_VALID)) 
#define DTE_IS_ACL_CAPABLE(v)(!!((v) & DTE_FLAG_ACL_CAPABLE)) 
#define DTE_REMOTE(v)(((v) & DTE_MASK_REMOTE) >> 8) 
#define DTE_LOCAL(v)((v) & DTE_MASK_LOCAL) 
  
#define DT_ROOM((ULONG) 0x00000007) 
#define DT_EQUIPMENT((ULONG) 0x00000008) 
#define DT_SEC_DISTLIST((ULONG) 0x00000009)

Definitions for Exchange address book and Message store error codes

The following contains error code definitions for the Exchange Address Book and Message Store, which have reconnection capability. The last call to a disconnected Global Catalog (GC) may result in the MAPI_E_END_OF_SESSION error, which would need to be retried.

Outlook's MAPI supports reconnection to a GC server without special reconfiguration, but some other error codes can be returned to the client.

MAPI_E_END_OF_SESSION
0x80040200
Returned when a connection has been disconnected.
MAPI_E_RECONNECTED
0x80040125
Returned when the Remote Procedure Call (RPC) connection token is out-of-date. If the token of the current transaction is different from the token of the connection that means it has reconnected, so MAPI_E_RECONNECTED is returned and can be treated the same as MAPI_E_END_OF_SESSION. The call should be retried.
MAPI_E_OFFLINE
0x80040126
Returned when the connection is offline. Typically this means that something has occurred in the environment, such as server failure or loss of network connectivity. This error is most likely to occur when using a cached mode profile and attempting to bypass the cache to communicate with the server. If the cache was never able to initially establish a connection to the server, it may be in the offline state in which MAPI_E_OFFLINE could surface.

Neither of the preceding two errors will be returned in all scenarios where they would likely appear to apply. In most cases, MAPI_E_NETWORK_ERROR or MAPI_E_CALL_FAILED will be returned. Neither will appear using the Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 download.

Definitions for Exchange Server Mailbox cached mode quotas

The following constant definitions are used by Microsoft Outlook 2010 and Microsoft Outlook 2013 to set the Exchange cached mode profile quotas that are equivalent to the Exchange mailbox quotas otherwise available only with an online profile.

#define PR_QUOTA_WARNING PROP_TAG( PT_LONG, 0x341A)
#define PR_QUOTA_SEND    PROP_TAG( PT_LONG, 0x341B)
#define PR_QUOTA_RECEIVE PROP_TAG( PT_LONG, 0x341C)

These properties map to their correspondent online properties and contain the same values in kilobytes. PR_QUOTA_WARNING maps to PR_STORAGE_QUOTA_LIMIT, PR_QUOTA_SEND to PR_QUOTA_PROHIBIT_SEND_QUOTA, and PR_QUOTA_RECEIVE to PR_PROHIBIT_RECEIVE_QUOTA.

Definitions for message format

The following constant definitions are values that are used to set the PidTagMessageEditorFormat Canonical Property.

#define EDITOR_FORMAT_DONTKNOW  ((ULONG) 0) 
#define EDITOR_FORMAT_PLAINTEXT ((ULONG) 1) 
#define EDITOR_FORMAT_HTML      ((ULONG) 2) 
#define EDITOR_FORMAT_RTF       ((ULONG) 3)

Definitions for using RPC over HTTP
