Topic: Operation with the nested message in OUTLOOK means VBA

Good morning!
Prompt, please, as it is possible by means of VBA to reach the nested message of the current letter to learn date of creation of the nested message and whether there is a possibility also to reach nestings which are in the nested letter?
I.e. I have a letter, I send it as nesting. The receiver needs to save the nested letter, and if in the nested letter there were any nestings to save them. All it is saved in a folder with date of creation of the nested letter.
At present I can save only the nested letter but how in it to reach all remaining - I will not understand?
