I want to set default apps for all AAD joined devices on our network.

Dear Luis1907  as mentioned by Mr. Eric better to open this topic on Microsoft Entra discussion space, however you can do it using below method: 

Step 1: Export Default App Associations

1. Configure Default Apps: Manually set desired default apps on a Windows 10 or 11 device via Settings > Apps > Default Apps.
2. Export App Associations: Open an elevated Command Prompt and execute the following command:

Bash

d i s m /Online /Export-DefaultAppAssociations:C:\DefaultAppAssociations.xml

This will generate an XML file (DefaultAppAssociations.xml) containing the current app associations.

Step 2: Review and Modify the XML File

1. Open the XML File: Use a text editor (e.g., Notepad) to open the exported XML file.
2. Verify Associations: Review the file's content to ensure the specified app associations are accurate.

Step 3: Upload the XML File to Intune

1. Access Intune Portal: Log in to the Microsoft Endpoint Manager admin center.
2. Create a New Configuration Profile:
• Platform: Windows 10 and later
• Profile Type: Templates > Custom
3. Configure OMA-URI Settings:
• Name: Default App Associations
• Description: Apply default app associations
• Use code
• Data Type: String
• Value: Paste the contents of the DefaultAppAssociations.xml file.

Step 4: Assign the Profile to AAD Joined Devices

1. Target Device Group: In the Intune portal, navigate to Assignments > Select Groups to Include.
2. Add Device Group: Add the desired AAD device group to the target list.
3. Deploy Profile: Save and deploy the configuration profile.

Step 5: Verify Configuration on Client Devices

1. Synchronize Devices: Ensure targeted AAD-joined devices have synchronized with Intune.
2. Test App Associations: Verify that the specified default app associations are applied on the client devices.
