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.

Outlook Add-ins are allowed to move emails to specific folder or even deleted folder?
If yes how can be done?
I didn't find anything about on the docs.
You can use EWS or Graph API for that. See Explore the EWS Managed API, EWS, and web services in Exchange for more information about EWS. More information specific to Outlook web add-ins can be found in the Call web services from an Outlook add-in article.
We are retrieving the email and attachments using the oAuth token from getCallbackTokenAsync in office.js JavaScript library and sending the token to the web application to retrieve them from EWS (~/EWS/Exchange.asmx) using SOAP request similar to the approach shown in https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/get-attachments-of-an-outlook-item
Could anyone please confirm that the deprecation of Outlook Rest API 2.0 will not affect the existing functionality. I am new to the Outlook add-in development and the documentation seems vast to digest.
https://devblogs.microsoft.com/microsoft365dev/outlook-rest-api-v2-0-deprecation-notice/
Do we need to register the add-in anywhere OR provide any permissions to the add-in specifically for getCallbackTokenAsync method to retrieve the token OR making the SOAP request to download attachments.
EWS remains unchanged for Outlook web add-ins. Make sure that you don't use the isRest option for the getCallbackTokenAsync call.
Take a look at the recent Office add-ins community call where this question was discussed in depth. Here is a screenshot for others:
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 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 an Outlook 2013 add-in that I'm developing. Its very simple - it forwards the selected email as an attachment to a specific address and then it deletes the email selected. (Really just moves it to the recycle bin).
If our organization upgrades to Office 365, is there anyway to replicate that functionality with the 'new' add-ins? The javascript API's don't seem to give any way of moving emails to other folders or otherwise 'deleting' them.
https://msdn.microsoft.com/en-us/library/office/fp142185.aspx
Is there another method/API for developing add-ins for Outlook 365?
Thanks!
Mail Apps are run in the context of items and JavaScript API for Office doesn't provide any methods for that. You need to use EWS or Office 365 API for getting the job done. Also see EWS Managed API, EWS, and web services in Exchange for more information.
