PropertyStreamHeaderTopLevel
Overview
PropertyStreamHeaderTopLevel holds the decoded 32-byte preamble of the __properties_version1.0 stream at the root storage of a MSG file. The header records the next available recipient and attachment IDs, the current recipient and attachment counts, and reserved padding fields. It is returned as the first element of the two-tuple produced by MsgReader.parse_message_property_stream().
from aspose.email_foss.msg import MsgReader
with MsgReader.from_file("message.msg") as reader:
header, entries = reader.parse_message_property_stream()
print(f"recipients={header.recipient_count}, attachments={header.attachment_count}")
print(f"next_recipient_id={header.next_recipient_id}")
print(f"property entries={len(entries)}")Properties
