I see a paper clip icon next to a message, but when I open it, the attachment is gone.
You may have received a message that contains a Level 1 e-mail security attachment file type. To help prevent the inadvertent spread of viruses, Microsoft Outlook compares the file type of each attachment in a received message with the file types on the e-mail security attachment file type list. If an attachment is a file type that can contain code that can run automatically without your consent, you cannot see or access the attachment.
Check the InfoBar at the top of the message to see the name of the file attachment you are unable to access.

Note If you created a custom form that included a Level 1 file type in the message body, your attachment will not be visible once you save and close the form. The InfoBar will not show the name of the blocked file attachment because custom forms do not display the InfoBar.
The shortcut I sent to others has disappeared from their messages.
Shortcuts with a file extension of .lnk or .url are Level 1 e-mail security attachment file types. To help prevent the inadvertent spread of viruses, Microsoft Outlook compares the file type of each attachment in a message you send with the Level 1 file types on the e-mail security attachment file type list. If the attachment file type is Level 1, recipients cannot see or access the attachment. Recipients can verify that this is why they are not seeing the shortcut by checking the message's InfoBar to see if it displays the name of your shortcut. You can then send them a message with a text link instead of the shortcut.
The View Attachments command on the shortcut menu is unavailable.

I can't send an encrypted message.
You might not have the intended recipient's certificate (public key). Ask the recipient to send you a digitally signed message, and then add their certificate to Contacts.
The certificate is now stored with your contact entry for this recipient.
To view the certificates for a contact, in Contacts, double-click the person's name, and then click the Certificates tab.
The digital signature on a message I received is not valid and not trusted.
There can be several reasons why the digital signature is not valid and not trusted. For example, the sender's certificate may have expired, it may have been revoked by the certificate authority (CA), or the server that verifies the certificate may be unavailable. Contact the sender of the message.
My message format changed when I sent a digitally signed message.
If you are using Rich Text Format for messages, and you send a digitally signed message, the message format is changed to HTML to help ensure correct processing of the security code. Some formatting may be lost in the conversion.
I receive a message when I try to send encrypted or digitally signed e-mail.
If you receive the message: "The Security Policy you selected does not allow one of the certificates in this security profile to be used," it means that the certificate in your default security settings has expired or has otherwise become invalid, or that your security policy does not accept your certificate. If you have set your security options to use labels on every message you send, the automatic configuration will not automatically notify you that your certificate has become invalid. To makes sure that the automatic configuration notifies you of problems with your default certificates, on the Tools menu, click Options, and then click the Security tab. Click Settings, and then click Security Labels. In the Policy module list, click None. If your security system does not allow you to choose None, contact your system administrator to get the correct certificates for your system.
If you receive the message: "Microsoft Outlook had problems encrypting this message because the following recipients had missing or invalid certificates, or conflicting or unsupported encryption capabilities," the most common cause is that you tried to send encrypted messages without having a copy of a valid certificate for the recipient. If you have multiple contacts for the recipient, you must send a message using the contact that has the certificate.
I sent a message with an S/MIME receipt request but received no return receipt.
An S/MIME receipt is not returned if either of the following is true:
My security label settings have disappeared from Microsoft Outlook.
You have changed your default security setting from S/MIME to Exchange Server security. Security labels, clear text signed messages, and S/MIME receipt requests require that S/MIME be your default security format. On the Tools menu, click Options and then click the Security tab. Click the Settings button and then in the Cryptographic format list, click S/MIME.
The security label settings aren't available.
I can't publish my certificates to the Global Address List.
I can't send an S/MIME receipt request.
You must be using Microsoft Windows 2000 or later.
You must have a valid security profile, including a valid certificate, to send an S/MIME receipt request.
If you are using an Internet e-mail account, such as POP3, an S/MIME receipt request is not sent until you click Send/Receive on the Microsoft Outlook toolbar.
Recipients of my labeled messages can't open the message.
I'm having problems synchronizing my Handheld PC or cell phone.
You may also receive error messages while synchronizing or when sending e-mail from some Handheld PCs.
Your security zone setting is set to the highest security level by default, which disables all active content in HTML messages.
