iOS and Android features for Secure Mail 编辑

This article describes the iOS and Android features that are supported on Secure Mail.

Support for Azure Government Cloud Computing

Secure Mail supports Government Cloud Computing (GCC) High for modern authentication (OAuth) on the Azure Active Directory tenant. Secure Mail is registered as an endpoint on the GCC High, to meet the mandatory requirement by Microsoft for all the GCC High service. For details, see What’s new for Azure Active Directory in Microsoft 365 Government.

With this change, you are routed to GCC High on the Azure Active Directory tenant for authentication. And the admin is required to allow permissions for Secure Mail on the Azure Active Directory tenant.

Prerequisites

Ensure that the global admin of Azure Active Directory performs the following:

• Download the latest version of Secure Mail on your device.
• Configure your Exchange account on the Secure Mail app, and allow app permission on Azure Active Directory for all users to sign in. Refer to the following screen.

Note:

These steps are specific only to the global admins as a one-time requirement. Once the app is granted access, you can simply upgrade from the App Store.

After the upgrade

After an upgrade, you are prompted for reauthorization after the expiration of the refresh token, which redirects you to GCC High on Azure AD. Validate the preceding workflow to ensure that the authorization request is sent to GCC High on Azure AD.

You can validate the workflow in one of the following ways:

• Secure Mail with app name Secure Mail-GCC High appears on the sign-in page in your Azure Active Directory tenant.
• Check the Secure Mail logs to confirm whether the redirects occur via https://login.microsoftonline.us after reauthentication.

Support for ICS files

In Secure Mail, you can preview the ICS files that you receive as attachments, and import it to your calendar as Events.

Contact picture in Secure Mail

In Secure Mail, view a picture of a contact when you add recipients in emails or meeting invites. For user help documentation on this feature, see the Citrix User Help Center article Show pictures of your contacts.

Manage your feeds

In Secure Mail, you can now organize your Feed card based on your requirements. For user help documentation on this feature, see the Citrix User Help Center article, Organize your email.

Use the Office 365 Exchange Server policy to define the Office 365 server address

In Secure Mail, a new policy called Office 365 Exchange Server is added under the section OAuth Support for Office 365. With this policy you can define the host name for the Office 365 mailbox present on Cloud. This policy also enables support of Office 365 for Government agencies. The host name is a single value such as outlook.office365.com. The default value is outlook.office365.com.

Support for encryption management

Encryption management allows you to use modern device platform security while also ensuring the device remains in a sufficient state to use platform security effectively. By using encryption management, you eliminate local data encryption redundancy since file system encryption is provided by the iOS or Android platform. To enable this feature, an admin must configure the Encryption type MDX policy to Platform encryption with compliance enforcement in the Citrix Endpoint Management console.

To use the encryption management feature, in the Citrix Endpoint Management console, set the Encryption type policy to Platform encryption with compliance enforcement. This enables encryption management and all the existing encrypted application data on users’ devices seamlessly transition to a state that is encrypted by the device and not by MDX. During this transition, the app is paused for a one-time data migration. Upon successful migration, responsibility for encryption of locally stored data is transferred from MDX to the device platform. MDX continues to check compliance of the device upon each app launch. This feature works in both MDM + MAM and MAM-only environments.

When you set the Encryption type policy to Platform encryption with compliance enforcement, the new policy supersedes your existing MDX Encryption.

For details about the encryption management MDX policies for Secure Mail, see the Encryption section in:

• MDX policies for mobile productivity apps for Android
• MDX policies for mobile productivity apps for iOS

When a device falls below the minimum compliance requirements, the Non-compliant device behavior policy allows you to select what action is taken:

• Allow app – Allow the app to run normally.
• Allow app after warning – Warn the user that an app does not meet the minimum compliance requirements and allows the app to run. This is the default value.
• Block app – Block the app from running.

Devices running iOS

The following criteria determine whether a device meets the minimum compliance requirements for devices running iOS:

• iOS 10 - An app is running operation system version that is greater than or equal to the specified version.
• Debugger access - An app does not have debugging enabled.
• Jailbroken device - An app is not running on a jailbroken device.
• Device passcode - Device passcode is ON.
• Data sharing - Data sharing is not enabled for the app.

Devices running Android

The following criteria determine whether a device meets the minimum compliance requirements for devices running Android:

• Android SDK 24 (Android 7 Nougat) - An app is running operation system version that is greater than or equal to the specified version.
• Debugger Access - An app does not have debugging enabled.
• Rooted devices - An app is not running on a rooted device.
• Device lock - Device passcode is ON.
• Device encrypted - An app is running on an encrypted device.

Support for responsive emails

Secure Mail has been optimized to deliver responsive email. Previously, email content with large tables or images were rendered incorrectly. This feature delivers email content as more readable on all supported devices irrespective of the email format and size.

Drag and drop calendar events

In Secure Mail, you can change the time of an existing calendar event by dragging and dropping the event. For user help documentation on this feature, see the Citrix User Help Center article, Change a calendar event time.

In Secure Mail, you can now organize your Feed card based on your requirements. For user help documentation on this feature, see the Citrix User Help Center article, Organize your email.

Auto Advance

In Secure Mail, when you delete a message in Conversations, you can choose which message you return to. To use this feature, navigate to Settings > Auto Advance. Then, select your preference from the available choices. For user help documentation on this feature, see the Citrix User Help Center article Delete and auto advance to an email in Conversations.

Drafts folder auto-sync

The drafts folder is automatically synced and your drafts are available across all your devices. This feature is available on devices running Office 365 or Exchange Server 2016 and later.

Note:

If your Secure Mail draft contains attachments, the attachments are not synced to the server.

For user help documentation on this feature, including a video, see the Citrix User Help Center article, Drafts folder auto-sync.

Support for single sign-on while using Microsoft Intune in MDM + MAM mode

For devices running iOS:

For devices running Android:

To be able to use this feature, ensure that Intune Company Portal app is installed on your device. Once you log in to the Intune Company Portal app, you are able to use SSO in the MDM + MAM mode without having to reauthenticate in Secure Mail using your credentials

Enhancements to Contacts

In Secure Mail, when you tap Contacts and select a contact, the details of that contact appear under the Contact tab. When you tap the Organization tab, the organization hierarchy details, such as Manager, Direct Reports, and Peers appear. When you tap the more icon on the top right of the screen, the following options appear:

• Edit
• Add to VIP
• Cancel

In the Organization tab, you can tap the more icon to the right of Manager, Direct Reports, or Peers. This action allows you to either create an email or a calendar event. The To: field of the email or calendar event is automatically populated with the details of Manager, Direct Reports, or Peers. You can compose and send the email.

Prerequisites

Ensure that Exchange Web Services (EWS) is enabled on your Exchange Server.

The contact details appear based on the organizational details (Outlook contact) fetched from Active Directory. For the correct details to appear for your contacts, ensure that your admin has configured your organizational hierarchy in Active Directory.

Secure Mail renders embedded resources while viewing an email

If the resources are present in your internal network, such as mails with image URLs that are internal links, Secure Mail connects to the internal network to fetch the content and render it.

Support for modern authentication

Modern authentication is OAuth token-based authentication with user name and password. This support includes support for Office 365 for internal and external Active Directory Federation Services (AD FS) or identity provider (IdP).

Allow Secure Web domains MDX policy for Secure Mail

In Secure Mail, some external URLs must open in a native browser rather than in Secure Web. As a result, by default, all URLs open in a native browser. You can, however, create a list of URLs that you specifically want to open in Secure Web. To do so, you configure an MDX policy in the Citrix Endpoint Management console called Allowed Secure Web Domains.

After you deploy the policy, a list of comma-separated URL host domains are matched against the host name portion of any URL the application would normally send to an external handler. Typically, you configure this policy as a list of internal domains for Secure Web to handle.

If you leave the policy blank, which is the default setting, all web traffic is sent to Secure Web, until you explicitly exclude the URLs from filtering or otherwise redirect the URLs. To redirect the URLs, you configure the Exclude URL filter for domains MDX policy. This policy indicates the URLs that must open in the native browser. This policy takes priority over the Secure Web domains policy.

You can configure these MDX policies for Android and iOS.

Example configuration of Secure Web domains policy

The following procedures show how to prompt users with Secure Mail for Android to open URLs in the native Chrome browser or Secure Web. On iOS, the steps show that URLs that would normally open in a Safari browser open automatically in Secure Web.

For Secure Mail for Android

1. In the App Interaction policy list, in Restricted Open-In exception list, enter {package=com.android.chrome}.
2. In the App Interaction (Outbound URL) policy list, in Allow Secure Web domains, add the DNS suffix of the internal site.

For other third-party browsers, use the following format, accordingly:

{package=<packageID of the browser>}

For Secure Mail for iOS

1. In the App Interaction (Outbound URL) policy list, in Allowed URLs, add +^safari:
2. In App URL schemes, add safari:
3. In Allow Secure Web domains, add the DNS suffix of the internal site.
