# 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](https://docs.zivver.com/en/user/owa/references/release-notes/6.0.0.html).

## 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](https://support.zivver.com/s/contactsupport?language=en_US) 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.
