Working on a project for a customer for which security is important, I was asked on how to secure attachments opening within Secure Mail.
This article is based on my research for iOS only, for now I will create another 1 for Android later.
First, with the iOS version of Secure Mail you don’t need any program to open/view an attached document type of Word, Excel, PowerPoint or Acrobat.
In fact, by default the App Interaction settings for Secure Mail are the following:
With that settings in place, within Secure Mail a user can open an attachment with every Microsoft applications which are free from Apple Store:
The customer for which I was working in this project, asked me to just provide the ability to open attachment with QuickEdit.
To do so, you will need to change the default Restricted Open-In exception list from:
com.microsoft.Office.Word,com.microsoft.Office.Excel,com.microsoft.Office.Powerpoint,com.microsoft.onenote,com.microsoft.onenoteiPad,com.microsoft.Office.Outlook
To:
com.bytesquared.office2ipad,com.citrix.office2forcitrix.ios
com.bytesquared.office2ipad is for iPad version of QuickEdit
com.citrix.office2forcitrix.ios is for iPhone version of QuickEdit
After doing that, if Citrix QuickEdit is not already provided to users, you will need to add it.
After doing all that configuration, the result is the following when trying to open a document:
You can only open document in QuickEdit even if Word, Excel or other Microsoft applications are installed on the device.
