Hi @Ankur Shah ,

You can use Get attachment Microsoft Graph API to read the properties, relationships, or raw contents of an attachment that is attached to a message in Outlook/Exchange Online.

Microsoft Graph Java SDK method to get the raw contents of an attachment that is attached to message :

GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();  
  
InputStream stream = graphClient.me().messages("Message-ID").attachments("Attachment-ID").content()  
 .buildRequest()  
 .get();  

Example :

However as mentioned in this Github issue, it seems there is some known issue with content() method in Microsoft Graph Java SDK and the below alternarive suggestion/workarround was provided in this GitHub issue post. Please refer the same for more information on this.

final InputStream result = new FileAttachmentStreamRequestBuilder(graphClient.me().messages("id").attachments("id").buildRequest().getRequestUrl().toString() + "/$value", graphClient, null).buildRequest().get();  

You can also refer the below addtional links on this Github Issue for more information:

Since this is a Microsoft Java SDK issue, I would advise you to raise an issue with GitHub SDKs support team for any questions on this.

Hope this helps.
