Receiving encrypted email

When you received a secure, encrypted email from a sender, open the attachment to launch a browser and authenticate. You then can decrypt and read the message.

Note: Red X icons in the browser mean your email program is blocking images — typically the logo or images of the sender’s organization. You can display or ignore them without affecting your ability to read the message.

• If you have not registered for Proofpoint Encryption, you will be prompted to create an account and choose a password on the Registration page. Select Continue when you are done. You will not be prompted to register again.
• If you already registered, or if your account already exists, you will be prompted to sign in and provide your password to decrypt the message. Select Continue.
• If you sign in and an editable field for your username is displayed, it means you have registered with Proofpoint Encryption before using a different email address. Enter the other address to sign in.

Forgot your password?

Use the Forgot Password link. You will receive an email with a link to reset and change your password.

Replying or forwarding

You can only reply or forward encrypted emails to the original sender or a WEC Energy Group email address. An error message will appear if you try to forward an encrypted email to an address with any other external domain name.

Using ‘Send me a copy’

Proofpoint Encryption will not automatically place copies of secure messages in your Sent folder. Use Send me a copy when you forward or reply to secure messages to receive a copy for your records.

Adding attachments

To add an attachment to a message, use the Attach a file link. Navigate to the file you want to attach, then select Add. The name of the attached file will appear in the dialog box. Select Upload when you are done adding attachments.

To delete attachments, select X to the right of the attachment.

Note: Attachments cannot exceed 15 MB combined.

Reading secure messages on smartphones

Some smartphones cannot download files, and some modify HTML files. Since your secure message is sent as an HTML attachment, you may not be able to read it on your smartphone. If you have trouble reading your secure message, follow the instructions to forward the message to another server . You will then be able to download the message to read it.

Troubleshooting

The following are common error messages and what they mean:

• “You authenticated successfully, but do not have permission to decrypt this message.”
  The message was not originally sent to you, or the administrator has disabled your ability to decrypt the message.
• “You authenticated successfully, but the decryption key for your message has been deleted.”
  The decryption key for this message has expired or has been deleted.
• “There was a critical error processing your request. There may be a problem with the system or your request.”
  Proofpoint Encryption is temporarily unavailable.
• “The message you are trying to read is corrupted and cannot be processed. Please contact the sender of the message.”
  The message has been altered or is damaged, and cannot be decrypted. Contact the sender and ask that they re-send the email.
• “There was an error retrieving the key for your message.”
  The key server is temporarily unavailable. Try again later.

Other Issues

Error with large HTML secure messages
HTML messages larger than 500 KB may generate a Large Message Warning. This limit applies to Firefox 3.X or later and Internet Explorer browsers when you reply to the message or forward it. It does not apply to plain text.

Using Outlook 2007 on Windows Vista
Do not save the SecureMessageAtt.htm attachment and try to open it. Open it from the email.
