[in] A pointer to an array that contains the names of the message classes to resolve. Message class names are always ANSI strings, never Unicode.
[in] A bitmask of flags that controls how the message classes are resolved. The following flag can be set:
Only message class strings that are an exact match should be resolved.
[out] A pointer to a pointer to an array of form information objects. If a client application passes NULL in the pMsgClassArray parameter, the ppfrminfoarray parameter contains form information objects for all forms in the container.
Client applications call the IMAPIFormContainer::ResolveMultipleMessageClasses method to resolve a group of message classes to forms within a form container. The array of form information objects returned in the ppfrminfoarray parameter provides further access to each of the forms' properties.
To resolve a group of message classes to forms, pass in an array of message class names to be resolved. To force the resolution to be exact (that is, to prevent resolution to a base class of the message class), the MAPIFORM_EXACTMATCH flag can be passed in the ulFlags parameter.
If a message class cannot be resolved to a form, NULL is returned for that message class in the form information array. Therefore, even if the method returns S_OK, do not assume that all message classes have been successfully resolved. Instead, check the values in the returned array.
