See IMAPIFormInfo : IMAPIProp.

Client applications call the IMAPIFormInfo::SaveForm method to save a description of the current form in the file with the given filename. SaveForm creates a configuration file.
Forms can be reinstalled by being selected from a list of form descriptor messages in a dialog box displayed by form library providers. The recommended extension for form descriptor messages is .FDM.
Call IMAPIProp::GetLastError if SaveForm returns MAPI_E_EXTENDED_ERROR, and check the returned MAPIERROR structure to determine the condition causing the error.
