Message classes - IPM.* vs IPF.*? RRS feed

  • Question

  • I'm trying to create a folder through EWS on an Exchange mailbox that uses a custom message class (so that it picks up my custom form). 

    When I tried to run this code, it failed:


    folder = new Folder(_service);

    folder.DisplayName =

    "Custom Folder";

    folder.FolderClass =



    Then I found this post: 

    It uses a FolderClass of "IPF.*" and that code works...

    What's the difference between using IPM.* and IPF.*?  Because all of the contacts I've been creating have used a message class of IPM.Contact.CMContact and it's worked just fine, but creating a folder with IPM.Contact.CMContact doesn't work...
