i want to set a flag for the messages which i had seen in my mail veiw, so that i can dislay them in different color, actually my mailserver is an iis smtp server. Iam using the statement to set flag

message[i].setFlag(Flags.Flag.SEEN,true);



while reading the message. But when i reading all the mail the message if iam checking the message whether the flag has set it returns false iam using this statement,


if(message[i].isSet(Flags.Flag.SEEN)),


. i think the flag hasn't been permanently set is there any way to do say pls reply immdtly.
