select Outlook element using Winium

[vimalraturi]

Hi,
I want to automate some outlook process by using Winium, I need to click on emails in outlook.
but I can't find email by XPath. can't use name property it got frequently change for different systems.
Currently, I used this code also but no positive response.

const string XPath = ".//*[contains(@name, 'Subject Test Mail')]";
var toEmailFinder = Winium.Cruciatus.Core.By.XPath(XPath);
var toEmail = Winium.Cruciatus.CruciatusFactory.Root.FindElement(toEmailFinder);
toEmail.Click();
