Requirements for OWA Assisted Mail Submission

To implement Zivver OWA Assisted Mail Submission (OWA-AMS), your organization must meet these requirements:

Zivver Outlook Web Access add-in v5 or newer is installed.
OWA-AMS is enabled for your organization.
You use one of the following mail servers or Secure Email Gateways (SEG):
- Microsoft Exchange Online as part of Office 365.
- A SEG that can:
  - Filter outbound messages based on a custom mail header.
  - Submit messages to a custom smart host.
- Any other mail server that can:
  - Filter outbound messages based on a custom mail header.
  - Submit messages to a custom smart host.

Use the latest version of the Zivver Outlook Web Access add-in. To find the most recent version, refer to the Zivver Outlook Web Access add-in release notes.

OWA-AMS enablement for your organization

To use OWA-AMS, you must enable this function for your organization. Without OWA-AMS enabled, your mail server or Secure Email Gateway (SEG) does not process sent Zivver messages. Please create a support ticket to request OWA-AMS enablement for your organization. You can choose from the following options:

Trial: Users will see a toggle at the bottom of the Zivver Outlook Web Access add-in side pane to turn OWA-AMS on or off.

Tip

It is advised to start the implementation of OWA-AMS in trial mode. This allows you to test the setup without disrupting the flow for all users.

Live: OWA-AMS is active without any visual indication for users. Every message sent with the Zivver OWA add-in is processed through the OWA-AMS flow.

Note

First implement OWA-AMS in your mail server or SEG. Otherwise, the server sends the Zivver message to the recipient as an unsecured email.

Requirements for mail servers or Secure Email Gateways

If your organization uses a Secure Email Gateway (SEG), you can implement OWA-AMS either in your mail server or in the SEG, depending on your organization’s requirements.

You can also implement OWA-AMS in a SEG or mail server other than Microsoft Exchange Online. That SEG or mail server must be able to filter outbound messages based on a custom mail header and submit filtered messages to a custom smart host.
