Mail safely from Outlook

Secure mailing is very easy to do directly from Outlook, using the Zivver Office plug-in.


  • You must be logged into Zivver via Outlook.
  1. In Outlook, click New Email mail_outline.
  2. Set up a message as usual. Add recipients. Enter a subject. Write a message.
  3. Click the toggle toggle_off next to the Zivver logo, to enable secure mailing.
  4. Click add attachments attach_file in the secure email bar to add an attachment (up to 5 TB).
  5. Click Send send.
    A new screen opens because Zivver checks the message for privacy-sensitive data. If the message contains privacy-sensitive data, you will receive a notification to send the message via Zivver.
  6. If you send a Zivver message to the receiving e-mail address for the first time, you will be asked to enter the verification method. Set the two-factor authentication and send the message. Verification ensures that only the right recipients have access to your message. Learn more about the different verification levels
  7. Wait a moment for the message to be sent.

Safety notifications

Zivver uses safety notifications to inform you when a certain rule is activated. The rules that are active depend on the settings of your organization. If there is sensitive information in your message or attachment (s), the secure mailing bar can automatically enter and change color.

Zivver has three different levels for safety notifications. Learn more about the different warning levels

Revoke Zivver message

Did you accidentally send a message to a wrong recipient? Did you send a wrong attachment? You can revoke the Zivver message. The message and the attachments immediately become inaccessible to all recipients.

Please read the topic on Message revocation for information on how to do this.

Read receipt

You can view a read receipt of every message sent. That way you know who read your message and who did not. You can find the read receipt in the form of a small envelope icon in the lower right corner of your sent Zivver message. Hold your mouse over the envelope icon to see who has read the message.

  • A gray, closed envelope mail means that the message has not yet been read by the recipients.
  • A gray, open envelope drafts means that the message has been read, but not yet by all recipients.
  • A blue, open envelope drafts means that the message has been read by all recipients.

The number next to the envelope indicates how many recipients have read the message.

Click the envelope or hold the mouse over the envelope icon to see who has read the message and who has not.
