Flags (4 bytes): This value is set to 0x00000000. Bits in this field indicate under what circumstances a short-term EntryID is valid. However, in any EntryID stored in a property value, these 4 bytes are zero, indicating a long-term EntryID.
ProviderUID (16 bytes): The identifier of the provider that created the EntryID. This value is used to route EntryIDs to the correct provider and MUST be set to %x81.2B.1F.A4.BE.A3.10.19.9D.6E.00.DD.01.0F.54.02.
Version (2 bytes): This value is set to 0x0000.
Pad (1 bit): (mask 0x8000) Reserved. This value is set to '0'.
MAE (2 bits): (mask 0x0C00) The encoding used for Macintosh-specific data attachments, as specified in [MS-OXCMAIL] section 2.1.3.4.3. The values for this field are specified in the following table.

U (1 bit): (mask 0x0080) A flag that indicates the format of the string fields that follow. If b'1', the string fields following are in Unicode (UTF-16 form) with 2-byte terminating null characters; if b'0', the string fields following are multibyte character set (MBCS) characters terminated by a single 0 byte.
R (2 bits): (mask 0x0060) Reserved. This value is set to b'00'.
L (1 bit): (mask 0x0010) A flag that indicates whether the server can look up an address in the address book. If b'1', server cannot look up this user's email address in the address book. If b'0', server can look up this user's email address in the address book.
