Invalid Certificate Error Message

[Guest]

On a system running XP and Office 2002, "Microsoft Update" downloaded and
installed the Office SP3 update. Everything had been working fine up until
this point.

Now when I try sending an email, I get this message:

Microsoft Outlook could not sign or encrypt this message because you have no
certificates which can be used to send from the email address (e-mail address removed)

Do I really need a certificate? If not, how to I disable this?

If I do need a certificate, how do I get it?

Thanks,

Tony

If you specify that the message is to be digitally signed, you'll get this
message if you don't have a cert installed. Simply disable the digital
signing, either by unselecting the "Digitally Sign Message" button on the
Standard toolbar (or by unchecking "Add digital signatiure to this message"
on View>Options>Security Settings) on a per-message basis, or by unchecking
"Add digital signature to outgoing message" on Tools>Options>Security.

If I do need a certificate, how do I get it?

Contact VeriSign or Thawte or some other certification authority if you need
one or turn off the options if you don't. You need one if you have to
either receive encrypted messages or you have to send messages that can be
proven to come from you.

Hi Brain,

I went into the Options and unchecked the option so a certificate would not
be required. It now allows me to send email. I really don't have a security
need that requires a digital certificate.

Thanks for the reply,

Tony

I'm glad it's working for you.
