# Verze:   1.0
# Datum:   2026-06-16
# Popis:   JNJ-native (MAPI / pywin32). Najde VSECHNY e-maily danemu prijemci
#          (default Hustak) napric vybranymi slozkami, ULOZI je jako .msg a
#          u kazdeho VYPISE diagnosticke MAPI vlastnosti precteni ze ZIVE
#          polozky (Message-ID 0x1035, SenderName 0x0C1A, SentRepresentingName
#          0x0042, addrtype 0x0C1E/0x0064, ReportText 0x1001, PrimarySendAccount
#          0x0E28, MessageFlags 0x0E07, item.Sent). Cil: porovnat, zda tyto
#          vlastnosti zustanou i v ulozenem .msg (olefile kontrola doma).
# Pouziti: Spustit v JNJ Pythonu (Thonny), Outlook s JNJ schrankou.
#          pip install pywin32 ;  python jnj_dump_recipient_msgs_v1.0.py
#          Skript NIC neodesila ani nemaze, jen CTE a uklada .msg kopie.
