The attachment object may have changed since this project was created. When I clone and run this in the browser today, I get an error when handling JSON for the attachment object.

I found that it happens because the $0_0 property is undefined, and the properties needed are available under the _data$p$0 property. I've modified the code and will send a PR.

There are important files that Microsoft projects should all have that are not present in this repository. A pull request has been opened to add the missing file(s). When the pr is merged this issue will be closed automatically.

Microsoft teams can learn more about this effort and share feedback within the open source guidance available internally.

Is there a way to update the web.config of an Outlook for web add-in to prevent the "... cannot be displayed in a frame" error?

Thanks

I am trying to develop an Add-in for Outlook, for that I have cloned this repo and have followed the instructions mentioned there.

My question is, when my add-in makes a request to https://localhost:44320/api/AttachmentService, it sends back a response with the following content:

{ "isError": false, "message": null, "attachmentsProcessed": 2, "attachmentNames": [ "avatar-1606916_960_720.png", "HnVmB0-k.jpg" ] }

But it does not tell me the URL of my attachment using which i can view the attachment.

Please help me

Thanks in advance

I was wondering if you could please tell me if the authentication used in this example is classed as basic and potentially should be replaced. I am currently developing an Outlook add-in that needs to save the emails and attachments of clients to our database. I have read in a recent blog post from Microsoft that basic authentication would be potentially stopped:

https://techcommunity.microsoft.com/t5/exchange-team-blog/improving-security-together/ba-p/805892

Is the methodology in this repository classed as basic, thus needs updating or can I still use it for the foreseeable future? Any advice regarding this topic would be greatly appreciate

When I click on the "Test attachments" button I get the following in the GC console. Any ideas how to fix this? Regards.

have developed an Outlook web add-in which can be used in Outlook native client, mobile app and outlook web to upload files to SharePoint online document library.
1. In the add-in, JavaScript calls a new Office.js API getAccessTokenAsync. This tells the Office host application to obtain an access token to the add-in. (Hereafter, this is called the access token because it is replaced with a second token later in the process.For an example of a decoded bootstrap access token.
2. If the user is not signed in, the Office host application opens a pop-up window for the user to sign in.
3. If this is the first time the current user has used your add-in, he or she is prompted to consent.
4. The Office host application requests the access token from the Azure AD v2.0 endpoint for the current user.
5. Azure AD sends the bootstrap token to the Office host application.
6. The Office host application sends the access token to the add-in as part of the result object returned by the getAccessTokenAsync call.
7. JavaScript in the add-in makes an HTTP request to a web API that is hosted at the same fully-qualified domain as the add-in, and it includes the access token as authorization proof.
8. Server-side code validates the incoming access token.
9. Server-side code uses the “on behalf of” flow to obtain an access token.
10. Azure AD returns the access token to the add-in.
11. Server-side code caches the access token.
12. Server-side code makes requests to exchange server to get attachment and upload attachment into SharePoint.
13. SharePoint REST API returns data to the add-in, which can pass it on to the add-in’s UI.
14. When the access token expires, the server-side code can use its refresh token to get a new access token.

This add-in is working in desktop and web outlook but is failing inconsistently in mobile devices using native outlook app.
 
In mobile device: it is working randomly for some accounts whereas the same code is not working for other accounts irrespective of the device.
 
We have verified for outlook versions, devices, account permissions level and do not see any issues.
While debugging we suspected that the problem might be processing documents from EWS server. In mobile outlook app the attachment token and ID values are different from desktop/web client for the same code. 

Code links – 
https://docs.microsoft.com/en-us/outlook/add-ins/get-attachments-of-an-outlook-item  

We are receiving the error in below snippet of code that is referenced from the above mentioned links.

ExchangeService service = new ExchangeService(); 
service.Credentials = new OAuthCredentials(request.attachmentToken); 
service.Url = new Uri(request.ewsUrl); 

var getAttachmentsResponse = exchangeService.GetAttachments(attachmentIds.ToArray(),
                             null,
                             new PropertySet(BasePropertySet.FirstClassProperties,
                             ItemSchema.MimeContent));

getAttachmentsResponse.OverallResult                  returning  ERROR in mobile for particular users


Need help to resolve this issue

Hello,
The example is showing information of attachments in read only mode. Do we have solution for reading attachments metadata in compose mode? I would like to show the attachment metadata like title, id and size in the add-in.

Recently our Outlook Addin had a validation comment about not being able to support Gmail for Mac because we implemented getting attachments using EWS as per this example. However, looking at this page we see

You cannot use Exchange Web Services (EWS) to access items in the Gmail mailbox. This means that you cannot use makeEwsRequestAsync or use an EWS callback token from getCallbackTokenAsync to make EWS calls directly. Instead, you can get the same type of access to the items in the mailbox by using the Outlook REST APIs.

Now, call this wishful thinking but our developers would totally love to see an example (similar to this one) for getting attachments using REST API. Pretty please! 😃 🙏🏽
