This article discusses the Android features that are supported in Secure Mail.
Undo sent mails
In Secure Mail for Android you can undo a sent mail. Once you tap the Send button, you get a toast message that allows you to undo the sent action. Tap Undo to revert the sent action and edit the mail, mail recipients, attach or remove attachments, or discard the mail
Attachments sync in Drafts folder
In Secure Mail for Android, when the Drafts folder is synced, the attachments are also synced and they are available across all your devices. This feature is available on devices running Exchange ActiveSync version 16 or later.
In-app view of PDF files
In Secure Mail for Android, you can view PDF files within the app, along with bookmarks and annotations. Also available is the enhanced view of other Microsoft Office attachments.
Use Web SSO for tunneling policy for setups running Modern authentication with Microsoft Office 365
In Secure Mail for Android, a new policy called Use Web SSO for tunneling is added. With this policy you can tunnel OAuth traffic to go over Secure Browse. To do so:
- Set Use Web SSO for tunneling policy to On.
- Select the Tunneled - Web SSO option in the Network access policy.
- Exclude any host names related to OAuth from the Background services policy.
Drag and drop calendar events
In Secure Mail for Android, 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.
Support for 64-bit apps for Google Play
Secure Mail for Android supports 64-bit architectures.
Improvements to the Pull to refresh UI in Secure Mail for Android
In keeping with Material Design guidelines, we have made minor improvements to the Pull to refresh feature. The sync timestamp is available at the bottom of the screen when you tap the hamburger icon.
Widget for Calendar agenda
In Secure Mail for Android, the Calendar agenda is available as a widget. From this widget, you can view the upcoming events in the Calendar for a week. This feature allows you to create a Calendar event, view an existing event and edit the details. The Block screen capture policy does not apply to the widget placed on the home screen. You can, however, disable the widget using the Allow Calendar Agenda widget policy.
Network access policy
In Secure Mail for Android, a new option called Tunneled - Web SSO is added to the Network Access MDX policy. Configuring this policy gives you the flexibility to tunnel internal traffic over Secure Browse and Secure Ticket Authority (STA) in parallel. You can also allow Secure Browse connections for authentication services, like NTLM, Okta, and Kerberos. When you initially configure STA, you must add individual FQDNs and ports of service addresses to the Background network services policy. If you configure the Tunneled - Web SSO option, however, you need not make these configurations.
To enable this policy for Secure Mail for Android in the Citrix Endpoint Management console:
- Download and use the .mdx file for Android. For details see steps in How mobile and MDX apps work.
- In the Network access policy, click Tunneled – Web SSO option. For more information, see App Network Access
Enhancements to Feed cards
The following enhancements have been made to the existing Feeds folder, in Secure Mail for Android:
- Meeting invites from all auto-synced folders appear in your Feeds card.
- View up to five Upcoming meetings in your Feeds card.
- Upcoming meetings now appear based on a 24-hour period starting from your current time. These meeting invites are categorized into Today and Tomorrow. In previous releases, upcoming meetings until the end of the day would appear in your feeds.
In Secure Mail for Android, viewing mail and calendar attachments is easy. For user help documentation on this feature, see the Citrix User Help Center article, View and attach files.
Print emails and calendar events

Report phishing emails with ActiveSync headers
In Secure Mail for Android, when a user reports a phishing mail, an EML file is generated as an attachment corresponding to that mail. Admins receive this mail and can view the ActiveSync headers associated with the reported mail.
To enable this feature, an admin must configure the Report Phishing Email Address policy and set the Report Phishing Mechanism as Report Via Attachment in the Citrix Endpoint Management console. For details about configuring MDX policies for Secure Mail, see MDX policies for mobile productivity apps.
In Secure Mail for Android, you can receive mail notifications from subfolders of your mail account.
- Ensure that the FCM-based push notification is enabled in the Endpoint Management console to get notifications for subfolders. For steps to configure FCM-based push notifications, see Push notifications for Secure Mail.
- The subfolder notification feature is not available for Lotus Notes Server.
To enable notifications for subfolders
Go to Settings and then under General, tap Notifications.
In the Notifications screen, tap Mail folders. A list of subfolders within the inbox appears.
Tap to select the subfolders you want to receive notifications from. Inbox is selected by default.
Enabling notifications for subfolders enables auto sync.

The notifications on the lock screen are available based on how your admin has configured the Control locked screen notifications MDX policy.
Meeting response buttons within the email
In Secure Mail for Android, meeting response buttons appear within the email. When you receive an email notification about meeting invites, you can respond to the invite by tapping on one of the following options:
Enhancement to attachments
In Secure Mail for Android, viewing attachments is simplified. For a better experience, inessential steps are removed, while attachment options that existed in the earlier releases are retained.
You can view attachments within Secure Mail app. The attachment opens directly, if it can be viewed using Secure Mail. If the attachment cannot be viewed using Secure Mail, a list of apps appears. You can select the required app to view the attachment. For user help documentation on this feature, see the Citrix User Help Center article, View and attach files.
Back button enhancements
In Secure Mail for Android, you can tap the back button on your device to dismiss the expanded options of the Floating Action button. If the Floating Action button is in the expanded state, tapping the back button on your device collapses the response options. This action takes you back to the message or event details view.
Admin steps to enable file attachments from the Gallery in Android
In Secure Mail versions 10.3.5 and later, users can’t attach images directly from the Gallery app if the Inbound document exchange (Open-in) policy is set to Restricted. If you want to keep this policy set to Restricted, but allow users to add photos from the Gallery, follow these steps in the Endpoint Management console.
Set Block gallery to Off.
Get the Gallery package ID for devices. Some examples:
- LG Nexus 5: com.google.android.gallery3d, com.google.android.apps.photos
- Samsung Galaxy Note 3: com.sec.android.gallery3d, com.sec.android.gallery3d.panorama360view, com.google.android.apps.photos
- Sony Expire: com.sonyericsson.album, com.google.android.apps.photos
- HTC: com.google.android.apps.photos, com.htc.album
- Huawei: com.android.gallery3d, com.google.android.apps.photos
Make the hidden policy InboundDocumentExchangeWhitelist visible:
- Download the WorxMail APK file and wrap the file with the MDX Toolkit.
- Find the .mdx file on your computer and change the file suffix to .zip.
- Open the .zip file and find the policy_metadata.xml file
- Search for and change InboundDocumentExchangeWhitelist from
- Save the policy_metadata.xml file.
- Select all the files in that folder and compress to create the .zip file.
Don’t zip the outer folder. Select all files inside the folder and compress the selected files.
- Click the resulting compressed file.
- Choose Get Info and change the file suffix back to .mdx.
Upload the modified .mdx file to the Endpoint Management console and add the list of Gallery package IDs to the now-visible Inbound document exchange whitelist policy.
Ensure that the package IDs are comma-separated:
com.sec.android.gallery3d, com.sec.android.gallery3d.panorama360view, com.google.android.apps.photos
Save and deploy Secure Mail.

Updates to background services
To meet the Google Play Background Execution Limits requirement on devices running Android 8.0 (API level 26) or later, we have upgraded Secure Mail background services. For uninterrupted mail sync and notifications on your device, enable Firebase Cloud Messaging (FCM) service push notifications. For more details about enabling FCM-based push notifications, see Push notifications for Secure Mail
Ensure that you turn on Mail notifications in Secure Mail settings on your device. For more details about this update, see this Support Knowledge Center article.
If you have not enabled FCM-based push notifications, background sync occurs once in every 15 minutes. This interval varies depending on whether the app is running in the background or the foreground.
When users manually update the time from device settings, the date in the calendar widget does not update automatically.
