How to get shared folder list of Calendar RRS feed

  • Question

  • Hi. buddys.

    I'm developing web application from Exchange Web Service

    so. I want to get shared folder in my Treeview.

    first of all.

    I made treeview of user calendar folder list.


    ExchangeService service = new ExchangeService();
    ExchangeServiceBinding esb = new ExchangeServiceBinding();
    service = new ExchangeService(ExchangeVersion.Exchange2010);
    service.UseDefaultCredentials = true;
    service.Credentials = new WebCredentials(pUserID, pPassword, pDomain);
    esb = new ExchangeServiceBinding();
    esb.Credentials = new NetworkCredential(pUserID, pPassword, pDomain);
    FolderView view = new FolderView(int.MaxValue);
    PropertySet pSet = new PropertySet(BasePropertySet.FirstClassProperties);
    view.PropertySet = pSet;
    FolderId parentFolderID;
    parentFolderID = "AAMkADM3OWU3MWE2LTg3MDQtNGVhNy05MTEzLWNhMDJkZGU2ZmNmMAAuAAAAAAAH1VD2ikcDRJ02ORHBlp0zAQA+yTdln0izT64gOklzkoHnAAAEATURAAA="; // this is from "IPF.Appointment" of WellKnownFolderName.MsgFolderRoot 
    parentFolderID = new FolderId(strParentFolderID); 
    ServicePointManager.CertificatePolicy = new clsSecurity();
    FindFoldersResults findResults = service.FindFolders(parentFolderID, view);


    so Finally I can get Calendar folder list.

  • The MRU lists are relative to the Outlook profile and pc they are being used on so EWS doesn't have access to this type of information.

  • Hi. Glen.

    What do you mean?


    You mean it doesn't get other's shared folder list from EWS?

    but, I can see  other's shared folder list on Exchange 2010 OWA.

    IS it just porssible OWA can get it?

  • As far as i know there are no EWS operations for enumerating shared folders (there are new operations for creating sharing folder requests in 2010 SP1) you can open up a shared folder using delegate access I'm not sure is your question about opening shared folders or enumerating what shared folders are available to a user ?

    One 2010 you have a few more options one method would be you could enumerate the IPM.Microsoft.WunderBar.Link object in the common view folders and if you look at the PR_WLINK_GROUP_NAME property you could then reconstruct the Oulook and OWA shared calendar hierarchies. I would suggest you look at this with a Mapi editor like Outlook Spy of MFC mapi which lets you see the properties available there is also doco on the Wunderbar link on
