Get the count of all emails which have been encrypted using EWS RRS feed

  • Question

  • Hi,

    Outlook has a feature which allows users to encrypt messages sent to a user. Please refer the attached image.

    Is there a way or Extended property which I can use to get the count of all such messages for a Outlook user using EWS.

    Please note, I need to make use of only EWS .

    Thanks in advance.

  • For SMIME messages the message itself should have an ItemClass or  IPM.Note.SMIME so you should be able to use ItemSchema.ItemClass to Filter or count messages that are encrypted using SMIME
