outlook-web-addins

I have created an Outlook add-in, which uses mailbox.getCallbackTokenAsync() function to authenticate with EWS API. For the majority of the add-in users, this works without issues. However, for some users, calling this function results in the "An internal error has occurred" error. This seems to occur just once, and subsequent calls to this function return token successfully. Users that experience issues use various Outlook versions - Outlook 16.0.6965.2115, Outlook 16.0.7571.2109, Outlook Mac 15.29, ... Do you have any idea what is the cause of this error? 来源： https://stackoverflow.com

I am trying to retrieve custom property value for an event using Microsoft Graph. The custom property was created by an Outlook Office.js Add-ing Here is request /v1.0/me/events/{id}?$expand=singleValueExtendedProperties($filter=id eq 'String {00020329-0000-0000-C000-000000000046} Name myCusProp') This returns a successful response from Graph but it does not return the singleValueExtendedProperty . The Outlook add-in, however, is still able to retrieve the property value from the same Event. { "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('{id}')/events/$entity", "@odata

I would like to update the content of my Outlook Web Add-in when Calendar event data is changed. Is there any possibility to catch kind of ItemChanged event in the web add-ins? I have found some projects with OnSend , but trying that way does not work, and there is only that event possible to catch. Currently the feature you are specifying is not a part of the product. However, we are actively investigating what types of events would be beneficial for the platform. We track Outlook add-in feature requests on our user-voice page . Please add your request there.

My add-in has a MessageComposeCommandSurface ExtensionPoint that adds a button to the ribbon when the user is composing a message. I expected the button to always be enabled when it is visible (e.g. when the user is composing a new message or replying to an existing one), but sometimes it is greyed out/disabled and I'm not sure why. Does anyone know the exact circumstances for when an add-in ribbon button is greyed out/disabled? Try to disable some COM add-in and then enable it again. In my case it helped to make buttons active. 来源： https://stackoverflow.com/questions/46697093/outlook-add-in

On this page https://github.com/OfficeDev/office-js-docs/blob/master/reference/outlook/tutorial-api-requirement-sets.md it is specified that both Outlook 2016 (MSI) for Windows and Outlook 2013 for Windows support Outlook API up to Version 1.4, but when we try to increase the minimal version in the manifest from 1.1 to 1.3, the addin works fine on web but does not show on both desktop versions. Currently I am working on Outlook Professional Plus 2016 with build number 16.0.4312.100, 64bit on Windows 10. I am trying a simple addin generated by yeoman office-generator, with only change is the

I'm trying to get all email headers from a selected Outlook email while inside an Outlook Addin. I've found the Preview API that should allow me to get the headers. This is what I have tried as of now Office.initialize = (reason) => { headerNames = ["Received-SPF"] Office.context.mailbox.item.internetHeaders.getAsync(headerNames, print); } print(asyncResult) { console.log(asyncResult.value); } The problem is when I start to put more headers, the API doesn't return them. The only ones I get are Received-SPF, DKIM-Signature and Authentication-Results. All other headers (Received, To, X-Microsoft
