outlook-addin

I am developing Outlook add-in which will work with shared mailboxes. Currently, office add-ins are not available on delegate scenarios but MS has released preview build which supports these scenarios. https://docs.microsoft.com/en-us/office/dev/add-ins/reference/manifest/supportssharedfolders My problem is since the manifest.xml has preview elements; I can't upload the it at outlook.office365.com under my add-ins . I get following error. This app can't be installed. The manifest file doesn't conform to the schema definition. The element 'DesktopFormFactor' in namespace 'http://schemas

So it seems that it is a fairly common question in CRM to try get the object type code when you have an entity name. But since I always have to do things the hard way, I have the reverse task: I have the object type code, and need to get the entity name. In general, the ultimate task is to take the the CRM regarding information on an email, and use it to query CRM for additional info. I can get the regardingID and the object type code easily. And for standard entities I can use a hardcoded lookup to get an entity name. But for custom entities, this won't work, as the object type code can be

I am using the following code to open the signed/unsigned Outlook messages and I display the content in WebBrowser control.

The file may not exist, you may not have

I'm developing add-in for Outlook 2013,I'm struggling with PR_INTERNET_MESSAGE_ID , I could easily get PR_INTERNET_MESSAGE_ID on archiving incoming mails, but it returns nothing on sending mail. Any help would be appreciated! Thank you! here is my code string PR_INTERNET_MESSAGE_ID = "http://schemas.microsoft.com/mapi/proptag/0x1035001F"; Microsoft.Office.Interop.Outlook.PropertyAccessor pal = mailItem.PropertyAccessor; string Internet_Message_Id = pal.GetProperty(PR_INTERNET_MESSAGE_ID).ToString(); That property is only sent after the message is sent. Exchange 2010/2013 sets that property for

I've not been able to find a whole lot on this anywhere. Let me start by saying I don't want to use the old Windows Form. I want to add a new WPF Window to my outlook 2007 addin project in visual studio 2008. The WPF Window template however does not show up. I was following this tutorial: http://msdn.microsoft.com/en-us/library/bb410039.aspx , which even had a picture of how you could add a new wpf window to your outlook 2007 addin.

Is it possible to tell either in the XML file or through OfficeJs if the add-in can use the REST API or if it needs to use the older EWS API? We have an Outlook add-in that needs to support OWA/O365 and Outlook 2016 with a stand alone exchange server.
