Microsoft Office Outlook could not sign or enrypt this message be.

[Guest]

I am using Outlook 2003 and have a digital ID from Comodo. If I send a
message signed with my digital ID to someon and they try to reply and they do
not have an ID they receive the following message.

Microsoft Office Outlook could not sign or encrypt this message because you
have no certificates which can be used to send from the e-mail address
(e-mail address removed). You can do either of the following:

Get a new digital ID to use with this account. On the Tools menu, click
Options, click Security tab, and then click Get a Digital ID.

Use the Accounts button to send the message using an account that you have
certificates for.

With two buttons labeled" Change Security Settings and OK.

I have checked my security settings and I am not sending messages encrpted.
All I want to do is send a digital ID so that receivers know that I sent the
message. I have never encountered this type of behavior with other email
clients using digital IDs and this behavior os confusing my customers. I am
going to disable my digital IDs and try to determine if I have a
configuration setting set incorrectly. Does anyoe know if this is the
behavior I should expect from Outlook? Is there something configured wrong
with my client? Does the behavior have anything to do with my certificate
authority?

Hi,

This error is usually caused by the fact that the other person has not
saved
your certificate in their address book....so it doesn't know which
certificate
to use to encrypt the reply.

The usage of email certificates is a little back to front.
You cannot send an email to someone and encrypt it with your Public
Key, you can
only encrypt the email to someone using their Public Key.
And in order to do that they must first send you a digitally signed
email so that
you can store their Public Key in your address book.
And visa-versa, you must send them your Public Key for them to store.

Also, with Outlook you must ensure that the digital email certificate
you
get matches exactly the email address you are using.
i.e. if your Outlook account is set for (e-mail address removed) and you get a
certificate
for (e-mail address removed) it will not work...only a certificate for
(e-mail address removed)
will work as that matches exactly the email account setting in Outlook.
