Invalid Certificate

[Christine]

I was trying to send an email to a client when this box poped up. I have
microsoft exchange, and i am able to send from that location. But when I send
from microsoft outlook i get the following error.

Microsoft office outlook cannot sign or encrypt this message becasue you
have no certificates which can be used to sent from the e-mail adress
'(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
Trust Center, click email security and then click get a digital ID.
use the accounts button to send the message using an account that you have
certs for.

I went to the site and there were a LIST of digi IDS.

Can someone help me? Does it matter which ID i choose? and how does this work?
thank you so much in advance!

Your sender digitally signed the message he sent you. Outlook assumes,
then, that youre reply should also be digitally signed. If you don't
have a certificate, Outlook won't find it and will present you with that
message.

You can't choose just any certificate. You must use a certificate that
has been created for you and validated by a Trusted Certification
Authority. If you don't have a cerificate, just disable replying with a
certificate. The error message won't happen then.

Thawte used to give out free e-mail certificates. They got acquired by
Verisign and after a couple years the free service vaporized. Comodo still
gives out free e-mail certs but they are only for personal or home use --
and that doesn't seem to apply to you. These free certs do NOT identify
you. They merely contain the e-mail address to verify the cert was issued
for that address.

The e-mail cert's e-mail address has to match the one you are sending
through in the account defined in Outlook. Otherwise there would be no
point in using the cert since you would be sending e-mail from a domain
different than specified in your cert. You can't be using a cert for your
Exchange account when you aren't using it to send a digitally signed e-mail.
You'll need to get an e-mail cert for your ccc.com domain.

However, since you mentioned Exchange, it is likely that you are sending
e-mail from a work/corporate network. That means you will have to buy an
e-mail certificate for business use. Do you actually have permission to
send e-mails using corporate resources and whose e-mails will trace back to
their hosts that do not specify your work e-mail address? You never
mentioned through WHOSE mail server you are sending the outbound e-mails
that do not specify your work e-mail address. If you are sending your
outbound e-mails through the company's Exchange server, they don't want you
specify a non-work e-mail address and they expect that e-mail traffic to be
work-related. It also means those are business e-mails (even if you abuse
their mail resources for personal e-mails) so you don't qualify for a free
e-mail cert (from Comodo). If, however, you do NOT use your company's mail
server and instead connect to your own e-mail provider to send your outbound
personal e-mails, you can get a free e-mail cert for that personal-use
e-mail account.
