“Email cannot be sent. Unable to find valid encryption certificate

for [E-mail address]” error message

This error indicates the LDAP Directory found in the Address Book Setup did not contain an encryption certificate for

the specified E-mail address. Encrypted E-mail can only be sent to recipients found in the global address book, and

each recipient must have an encryption certificate. Verify that the intended recipient is in your global address book.
