Hi Sergey,

Thanks for your response. I had a look at the suggested links. I tried to use the priority and/or importance in my code. Somehow, I never see 'High' importance. I am using Outlook to read email. The class that sends the code is something like this.

Declare SHORT InternetGetConnectedState In wininet.Dll;
    INTEGER @lpdwFlags, Integer dwReserved
lConnect=This.displayState()

If lConnect
    iMsg = Createobject("CDO.Message")
    iConf = Createobject("CDO.Configuration")
    Flds = iConf.Fields
    With Flds
        .Item("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2
        .Item("http://schemas.microsoft.com/cdo/configuration/smtpserver") = 'mySmtpserver'
        .Item("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25
	.Item("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 90    	
        * Set Priority/Importance to High. 
        .Item("urn:schemas:httpmail:importance") = 2  
        .Item("urn:schemas:mailheader:importance") = "High" 		    
    
        .Item("urn:schemas:httpmail:priority")   = 1 	  
        .Item("urn:schemas:mailheader:priority")   = 1 		

        .Item("urn:schemas:mailheader:X-MSMail-Priority") = "High" 
        .Item("urn:schemas:mailheader:X-Priority") = 1 
		    
    .Update
    ENDWITH
    
    With iMsg
        .Configuration = iConf
        .To = This.To
        .CC = This.CC
        .BCC = This.BCC
        .From = This.From
        .Subject = This.Subject
        IF NOT EMPTY(This.HTMLBody) 
        	 .HTMLBody = This.HTMLBody 
        ENDIF 
        .TextBody = This.TextBody
        
        .Send
    ENDWITH
 ENDIF 

Could you please suggest which commands are required to set the priority/importance high that will work on most email clients, including Outlook?

Thank you so much.
