I got the answer from Dmitry (the OutlookSpy creator), so if anyone is
interested the function is below.
function HexFromBin(lpb : pointer; cb : DWORD):string;
var HexStr:string;
i:integer;
begin
SetLength(Result,2*cb);
for i:=0 to cb-1 do begin
HexStr:=IntToHex(TByteArray(lpb^)[i], 2);
Result[2*i+1]:=HexStr[1];
Result[2*i+2]:=HexStr[2];
end;
end;
to convert it back, use:
function BinFromHex(hex : string):string;
var HexStr:string;
i:integer;
begin
SetLength(Result,Length(hex) div 2);
for i:=1 to Length(Result) do begin
HexStr:='$'+Copy(hex, 2*i-1, 2);
byte(Result[i]):=StrToInt(HexStr);
end;
end;
Its return value can be cast to PEntryID as
PEntryID(PChar(BinFromHexResult))

EntryID?
In fact I can't find any references to this function apart from in the
link below, and it does say that the function may be discontinued. The
only MapiUtil.h I can find has no reference to this function. Has anyone
used this call.

Thanks for that, does anyone have the MAPIUtils.h file translated?

there is a function (pardon my C++)
HrSzFromEntryID(ULONG cb, LPENTRYID lpEntryID,
LPTSTR FAR *lpsz);
in MAPI32.DLL that i think does what you want.
Have a look at:
