When we send emails to aoutlook accountwith "Rights Management options" which are "Encrypt, Do not forward, Confidential, Confidential view only" options, therecipients are not allowed to decrypt the emails. They(outlook recipients) can see the plain text without doing any thing(decrypting).But when we send those encrypt emails togmail or yahoo,therecipients have to use one-time pass code to obtain the plain text. The problem happens onlybetween outlook accounts.
Is this a problem of outlook or what is the reason behind this situation? Is there anyway to resolve this?
