Redemption.SafeMailItem error in outlook

Question

Hi 

I'm using the below code to get the sender email id.

public static string GetSenderEmailAddress(Outlook.MailItem mailItem)
		{
			try
			{
 				int PR_EMAIL = 972947486;
				int PR_TYPE = 203292702;
				string senderEmailAddress = string.Empty;
Redemption.SafeMailItem safeMailItem = new Redemption.SafeMailItemClass();
safeMailItem.Item = mailItem;
string type = safeMailItem.get_Fields(PR_TYPE).ToString();
System.Windows.Forms.MessageBox.Show("type : " + type.ToString());
}
}

I'm getting an in this line "string type = safeMailItem.get_Fields(PR_TYPE).ToString()"  

Error : Object reference not set to an instance of an object. 

i'm sending the mailItem like this

Outlook.Inspector inspector = SingleOutlookRef.Instance.OutlookApp.ActiveInspector();
Outlook.MailItem mail = (Outlook.MailItem)inspector.CurrentItem;
string email = GetSenderEmailAddress(mail);

If i send the mail item like this it will work fine

Outlook.Explorer _explorer = SingleOutlookRef.Instance.OutlookApp.ActiveExplorer();

for (int i = 1; i <= this._explorer.Selection.Count; i++)
                    {
                        if (this._explorer.Selection[i] is Outlook.MailItem)
                        {
                            string email = GetSenderEmailAddress(mail);
                        }
}

Thanks

PR_SENDER_ADDRTYPE_A property is only present on the sent or received messages.

No MAPI property is guaranteed to be available, you need to test that you get back a valid value before you call ToString().

Change the line

string type = safeMailItem.get_Fields(PR_TYPE).ToString()

to

string type = "";

object v = safeMailItem.get_Fields(PR_TYPE);

if (v != null) type = v.ToString();
