block attachments on outlook mobile application
This can be done, but it will depend on your licensing. You will have to control the app with MAM via Intune. Then you can set policy for Outlook, SharePoint app, OneDrive, etc.
If you are looking for broader protection capabilities beyond what’s included in Office 365, you can subscribe to Microsoft Intune, which is part of the Microsoft Enterprise Mobility Suite. Intune provides mobile application management (MAM) capabilities for Outlook and other Office mobile apps in addition to the conditional access and device management capabilities outlined above. With Intune MAM, you can restrict actions such as cut, copy, paste, and “save as” of corporate data between Intune-managed apps and apps that are not managed by Intune. Additionally, the Intune-managed Outlook apps include a new multi-identity management feature that enables users to access both their personal and work email accounts in the same Outlook app while only applying the Intune MAM policies to the user’s work account –
this provides a much more seamless user experience.
Naveen_PandeyDid you end up finding a solution to this?
Microsoft says that we cannot currently block users from sending or forwarding emails with attachments from the Outlook app. The only thing that we would be able to edit in regards to the attachments included in emails is if the user can save it onto their device or not. You can block your users from doing so by using Conditional Access. Below I have attached further information on how you can use Conditional Access to block your users from downloading/saving attachments from Outlook on managed devices:
This includes the instructions on how to create App-based Conditional Access policies. Here you will be able to block your users from downloading attachments from the Outlook application:

To block the attachments specifically, you would need to go to the 'Session' blade when creating a new Conditional Access Policy and select 'User Conditional Access App Control'. From the drop-down menu, you need to select 'Block Downloads'. I have attached a screenshot of how it would appear below:
