When I send an email, how do I request read confirmation, delivery confirmation, and set the priority of the email?

In the “TTMSFNCCloudMicrosoftOutlookMailItem” class, it is implemented as read-only

    property IsRead: Boolean read FIsread default False;
...
    property Importance: string read FImportance;

Hi,

Please note that the read-only items are only intended to be used for received mail items.
Unfortunately it's currently not supported to get read/delivery of sent mail or set the priority of the email item.
However these are good suggestions and we'll investigate if these features are available in the Outlook Mail API and if it is possible to implement these in a future version.
