Emails in Non-IPM subtree can be searched out when enable "Use Cached Exchange Mode" option in outlook 2016 RRS feed

  • Question

  • I moved a mail to a new created folder in non-IPM subtree. The email can not be seen in inbox. But I could search it out by subject when enable "Use Cached Exchange Mode" option in outlook 2016. The previous results will not be discovered when I disabled the option and search again.
    Is the current behavior normal in outlook 2016?

  • Hi Simon,

    What's the folder structure of your mailbox? What does "non-IPM subtree" refer to in the description? How did you create a new folder in the non-IPM subtree? If possible, could you provide a screenshot so that we can understand it clearly and try to reproduce this issue here?

  • I created a subfolder under Root folder, with the c# code as follows:

    var folder = new Folder(this._es);
    folder.DisplayName = "TestSearch";
    var isHiddenProp = new ExtendedPropertyDefinition(0x10f4, MapiPropertyType.Boolean);
    folder.SetExtendedProperty(isHiddenProp, true);

    According to the description of the MSDN document, the folders created under ROOT are in the Non-IPM Subtree.
