VERIFY THE DIGITAL SIGNATURE ON A SIGNED MESSAGE YOU RECEIVE
For additional security, you can check digital signatures on messages
before opening them. In some cases the signatures may not be
available.
1
Open the message that has been digitally
signed.
2
At the top of the message, press View Signature
Status.
3
Press [Menu] Check Certificate.
There can be several reasons why a digital signature is not
valid. For example, the sender’s certificate may have expired,
it may have been revoked by the certificate authority, or the
server that verifies the certificate is unavailable. Contact the
sender to report the problem.
S/MIME encryption and digital signatures for Windows Mobile-
based devices are available only with Exchange Server 2003
Service Pack 2 or a later version that supports S/MIME.
If you aren’t using one of these products, or have not yet
synchronized, these options are unavailable.
