IMAPISupport : IUnknown

Applies to: Outlook 2013 | Outlook 2016

Provides implementations for tasks that are typically performed by service providers and message service entry point functions. Service providers receive a pointer to their support object when MAPI calls their provider object's logon method. Message services receive their support object pointer in the call to their entry point function.

Member Description
GetLastError
Returns a MAPIERROR structure that contains information about the previous support object error.
GetMemAllocRoutines
Retrieves the addresses of the MAPI memory allocation and deallocation functions (MAPIAllocateBuffer, MAPIAllocateMore, and MAPIFreeBuffer).
Subscribe
Registers an advise sink to receive notifications through MAPI.
Unsubscribe
Cancels the responsibility for sending notifications that was previously established with a call to the Subscribe method.
Notify
Sends a notification of a specified event to an advise source that originally registered for the notification through the Subscribe method.
ModifyStatusRow
Modifies the status table by adding a new row or modifying an existing row.
OpenProfileSection
Opens a section of the current profile and returns an IProfSect pointer for further access
RegisterPreprocessor
Registers a transport provider's preprocessor function (a function that conforms to the PreprocessMessage prototype).
NewUID
Creates a new MAPIUID structure to be used as a unique identifier.
MakeInvalid
Marks an object as unusable.
SpoolerYield
Gives control of the CPU to the MAPI spooler so that it can perform any tasks it considers necessary.
SpoolerNotify
Notifies the MAPI spooler of a change in status or a request for service.
CreateOneOff
Creates an entry identifier for a one-off address.
SetProviderUID
Registers a MAPIUID structure that uniquely represents the service provider.
CompareEntryIDs
Compares two entry identifiers to determine whether they refer to the same object.
OpenTemplateID
Opens a recipient entry in a foreign address book provider.
OpenEntry
Opens an object and returns an interface pointer for further access.
GetOneOffTable
Returns a pointer to the MAPI one-off table (a list of templates that all address book providers support for creating new recipients).
Address
Displays the common address dialog box.
Details
Displays a dialog box that shows details about a particular address book entry.
NewEntry
Adds a new recipient directly to an address book container or to the recipient list of an outgoing message.
DoConfigPropsheet
Displays a configuration property sheet.
CopyMessages
Copies or moves messages from one folder to another folder.
CopyFolder
Copies or moves a folder from its current parent folder to another parent folder.
DoCopyTo
Copies or moves all properties of one object, except for specifically excluded properties, to another object.
DoCopyProps
Copies or moves one or more properties of an object to another object.
DoProgressDialog
Retrieves a progress object that displays a progress indicator.
ReadReceipt
Generates a read or nonread report for a message.
PrepareSubmit
Prepares a message for submission to the MAPI spooler.
ExpandRecips
Completes a message's recipient list, expanding particular distribution lists.
DoSentMail
Processes a sent message.
OpenAddressBook
Provides access to the address book.
CompleteMsg
Performs postprocessing on a message.
StoreLogoffTransports
Requests the orderly release of a message store.
StatusRecips
Generates delivery and nondelivery reports.
WrapStoreEntryID
Converts a message store's internal entry identifier to an entry identifier in the MAPI standard format.
ModifyProfile
Makes changes to a message store profile section permanent.
IStorageFromStream
Implements a storage object to access a stream.
GetSvcConfigSupportObj
Creates a message service support object.

Remarks

Address books, message stores, transport providers, and message services each have their own support objects. Service providers and message services call the methods in their support objects as part of their implementations of other interface methods. Each different support object has complete implementations of the methods that apply to its caller; the methods that are not applicable return MAPI_E_NO_SUPPORT. Address book provider support objects have implementations for the following methods:
