Return receipts

some weeks ago i wrote a topic asking you how to enable return receipts for email messages.some one answered me to go on the basic tab in the messaging configuration and to turn on the return receipts option.

so i did it and now return receipts are working only from the domino server out.

for example if someone send me a message with a return receipt, lotus notes sends it.

instead, if i send an email asking the reader to confirm the read of the message, the user is not prompted to send it and nothing happens.

can anyone tell me something about that and help me working the problem out^?

thanks in advance

What mail client are they using? Not all mail clients are configured to handle return receipts.

they are using ms outlook and the options are set to ask for every receipt to send
