Thank you for replay.

The data i need to store are user's details id, user name, ....

Each user has his own folder and sub-folders and also may have other
users folders (delegate)
and to these folders i need to store data. I think it's better to
store hidden item per user's folder
e.g. i have folder AAAAA inside this folder i create hidden item with
user's details, for subfolder
i wouldn't ceate hidden item, cause i can check where i locate in
hierarchy


How i set named properties to hidden item via redemption??
that's what i do:

...........
.........
RDO.RDOFolder rFolder = RdoSession.GetFolderFromID(folderEntryID,
folderStoreID, Type.Missing);
RDO.RDOItems rHiddenItems = rFolder.HiddenItems;

/*i will identify my hidden item by subject.*/

..... i check here if item with such subject already exists


rHiddenItem = rFolder.HiddenItems.Add("IPM.Note");
rHiddenItem.Subject = ... some constant string .....;
rHiddenItem.Save();

here i shlould add named properties, how should i add them ?? by help
of
MAPIUtils.HrSetOneProp(rHiddenItem.MAPIOBJECT,
propID, .................
or there are other posibilities?? and also for get these properties.


Thanks in advance.

1. Your code should be adding the hidden item only once. Check that the
message already exists in the HiddenItems collection (pass the appropriate
subject to the RDOItems.Item method). If NULL is returned, call
HiddenItems.Add.
2. A property can be added using RDOMail.Fields - see
http://www.dimastr.com/redemption/rdo/MAPIProp.htm . There is abolsutely no
reason to use MAPIUtils object in this case.

Thanks for replay,

In case i'll use RDOMail.Fields i yet need use the GetIDsFromNames
cause i don't know the ProgTag of
named property. So it's same like use the MAPIUtils object .

Am i right??

TNX in Advance.

You *can* use GetIDsFromNames (which RDOMail exposes), but you don't have
to - the RDOMail version of fields also takes a DASL property name
(string) - in that case Redemption will call GetIDsFromNames internally:

Prop =
RDOMail.Fields("http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/8582000B")

I see, but Dmitry in DASL 8582000B is my PropTag?? Do you mean that i
should store it??
I don't inderstand, Also in your samples there are only getters of
properties and no setters.


Thanks in Advance.

Yes, the DASL name includes the GUID and id.
Look at a message which has your custom property set with OutlookSpy (url
below) - click IMessage, locate the property, look at the DASL edit box on
the right hand side of the window. You can hardcode that DASL name in your
code.
Setting a property is not any different from reading it:

RDOMail.Fields("http://schemas.microsoft.com/mapi/id/{00062008-0000-0000-C000-000000000046}/8582000B")
= SomeBooleanValue
