If you develop custom information store providers that support Unicode, when you copy folders that contain subfolders from the Exchange Server information store to the custom information store, the subfolders in the sample information store may be created with truncated subfolder names.
This problem can occur because the call to the IMAPIFolder::CreateFolder() function passes the ulFlags parameters as 0, which implies that the string is American National Standards Institute (ANSI), even though the string that is passed is Unicode. According to documentation, the ulFlags variable should be set to MAPI_UNICODE if the passed-in strings are in Unicode format. If the MAPI_UNICODE flag is not set, the strings are in ANSI format.
