I am currently looking for a good JS library to use for my addin. And I came across this project : MSGRAPH-SDK-JAVASCRIPT
I tried to read through their project details but could not find out definitively if they support the SSO-OBO flow for addins.
Has anybody used the said library successfully for an SSO-OBO flow?
Thank you very much.
Single sign on and MS Graph SDK are different things. You can use SSO to deal with Graph API from Outlook web add-ins. See Using Single Sign-On (SSO) with Office Add-ins for more information.

I am working on an asp.net web form that has users with different O365 serviceses.
I mean they are not on the same AD, but come from different businesses.
I'm think they need to enter a username and password for their own system and then read the information.
Is there a way to access this calender information in C#?
I know there is Microsoft Graph, but can it be used with only a username and password without creating an applikation in Azure.
MS Graph is the most stable and efficient way of accessing O365 information nowadays. However, you may still use EWS or Outlook REST APIs, see Explore the EWS Managed API, EWS, and web services in Exchange for more information.
Here is what MS states in MSDN:
Microsoft recommends using Microsoft Graph to access Outlook mail, calendar, and contacts. You should use the Outlook APIs directly (via https://outlook.office.com/api) only if you require a feature that is not available on the Graph endpoints.
See Overview of using the Outlook REST APIs for information.
I'm currently using Microsoft Graph, but have been running into its limitation on the request size. Seeing as how the Outlook REST API doesn't have that limitation and is supposed to be very similar to the Graph API for mail related functions, I wanted to use the Outlook API for sending messages with larger attachments.
But is there a way to get application level permissions with the Outlook REST API? Or make calls without a user? The authentication approach I'm using with Microsoft Graph is the one outlined at https://learn.microsoft.com/en-us/graph/auth-v2-service and it would be nice to be able to do the same with the Outlook API.
My app is registered at the Microsoft Application Registration Portal, but the permissions there are only for Microsoft Graph. I have seen an article that mentions being able to edit the manifest in order to get permissions working with other APIs (like the Outlook API), but wasn't too sure about that.
I am developing an Outlook Add-In, that will work in Office365 for both Web version and Desktop client and will able to upload files attached with the email to One-drive. Is it possible to authenticate and upload the files without user interaction(i.e. like opening popup, and providing user id and password etc).
Thanking all for your suggestions in advance.
Yes, Its possible.
What you have to do is :
1) create OutlookAddin solution with help of visual studio template.
2) It will add two projects in that solution OutlookAddin and OutlookAddinWeb.
3) Here OutlookAddinWeb is simple asp.net project that you have to covert into MVC Web API or you can add in new MVC Web API project after removing the existing OutlookAddinWeb.
4) Now,You can Microsoft Graph Client dll to use graph api functionalities to upload file in One Drive.
Note : The important thing you shouldn't forget about implementing authentication using OWIN API that is providing single sign-on as it is your main concern here

I'm currently working on a project where I'm sending and updating Appointsments. I would like to do this without the use of ActiveX since I don't want to be limited to IE. I've been googeling for quite some time now, but I couldn't find anything that helped, so here's my question. Is there any way I can access or update appointments without the use of ActiveX.
We also have access to the OutlookWebApp, so maybe there's an interface there. Would be great if someone had an idea. Thanks in advance and
Greetings Chris
You can use Exchange Web Services (web or desktop app) or the EWS Managed API (desktop app only) to access data in Exchange Mailboxes: https://msdn.microsoft.com/en-us/library/office/jj162981.aspx.
If you are working with Office 365 mailboxes you can use the Outlook REST or Microsoft Graph APIs: https://dev.outlook.com/
If your solution requires a UI in Outlook Online (OWA) then you can access contextual data (i.e. the current email or appointment) with an Outlook Add-in (you can use EWS requests from it as well): https://dev.outlook.com/reference/add-ins/
I have written an Outlook Add-In using the "standard" approach, which is a COM Add-In, compatible with Outlook Windows desktop versions.
I'm doing now a research about the capabilities of the new Office API which uses Javascript/HTML and is compatible with Outlook 2016 Windows/Mac and Web.
However, the resources seem really limited, where can I the information what functionalities that API provides i.e. in scope of the Calendar functionality of Outlook?
You can get started using JavaScript APIS using this link : https://dev.outlook.com/MailAppsGettingStarted/GetStarted
API Reference : https://dev.outlook.com/reference/add-ins/
This API provides access to mail/calendar item. This APIs are supported in Windows Outlook 2016 and Outlook Web Mail access client.
Hope it helps.
You are right, the functinality is still limited. See https://dev.outlook.com/ for more information about available APIs. But you may also find the EWS helpful. Read more about that in the EWS Managed API, EWS, and web services in Exchange section.
