Intune policy for controlling Outlook attachments

[ghost]

Describe the ~bug~ question: The iOS Outlook application displays a message to users "file format is not supported" when an encrypted zip file is found in an email attachment. Is there anyway using Intune Policies to inform Outlook to open the attachment in a different application?

To Reproduce Steps to reproduce the behavior:

1. Open Outlook and load email with attached zip Outlook Test.zip
2. Click on the attachment to see the error

~Expected~ Desired behavior: It would be great to somehow specify as an Intune policy that a .zip file should be handled by a different Intune Managed Application by defining the bundle id.

Screenshots and logs: Currently, a user must go through a complicated workflow to pass the .zip file from Outlook to the application to process the .zip file. The user experience is poor and it could be greatly improved by setting default application handling by attachment file type within Intune. Video of current workflow

Smartphone (please complete the following information):

• Device: Any
• OS: Any

Intune App SDK for iOS (please complete the following information):

• What version of the Intune SDK are you using? Are you using the latest version?

• What platform is your app based in (native, Xamarin based, Cordova, etc)?

• For errors during build, does the app build without Intune SDK integration?

• For errors post build, does the app launch without being Intune SDK integrated?

• Who is the customer?

• Do you see a trend with it only being reproduced on a specific device?

Additional context: I work for PKWARE. We create encrypted ZIP files that are frequently emailed in organizations. We recently launch an Intune wrapped version of our application and are looking for a way within Intune to improve the user experience App Store Listing

This might be better address with the Outlook team as well, but I figured I would ask if there is some way to do this in the current Intune SDK

Hi @pk-jdale, as far as I'm aware there is no way to share content to a specific app on iOS based on bundle ID. Something like this could be accomplished if your app declared a custom URL scheme that it handled, which Outlook could then invoke a URL with that scheme which pointed to a zip file, but this would be a feature request for the Outlook team. Intune custom app config could potentially be used to configure this behavior, but actual implementation would need to be done on the Outlook side.

That's what I figured, but I wanted to check here first. Thanks for the follow up.
