Other Intune-related topics, including unsupported scenarios and platform-specific behaviors
To find your documents in Intune, you may want to ensure that you are using the correct applications and that they are properly configured. Since you mentioned using Excel to add attachments to emails, make sure that the applications you are using are installed and managed through Intune. If you are unable to attach photos or documents, it might be due to specific permissions or settings that need to be adjusted within your Intune configuration.
Additionally, if you are using an Android Enterprise enrolled device, ensure that you have a File Explorer application approved and assigned from the managed Google Play store, as this is necessary for attaching files in certain applications.
If you continue to experience issues, consider checking the Intune documentation for guidance on managing and accessing files and documents within the applications you are using.
