阅读更多关于 Outlook Add In - Side Loaded Custom Add In disappears after I close the Windows Store from Outlook

问题 Very perplexing I am developing an Outlook Add-In to open a pane from a button on the compose email window. I have loaded into a test account on outlook.com, and it works perfectly. When I go to side-load the add into Outlook Desktop (by loading the manifest XML directly by file), the system accepts it. However, when I close the Microsoft Add-In Store window, the add-in is not in the compose email, AND when I go manage my add-ins, the manifest I loaded is not there. The add-in is designed to

阅读更多关于 Trusted way to get the host origin of an Office add-in

问题 I'm currently implementing an Outlook Add-in. It shows the user a pop-up window whenever the user is about to complete a potentially dangerous action, to protect against clickjacking attacks. I was hoping not to have to show the user the pop-up window every time they use the add-in -- only the first time they use it from a new host origin. Is there a way to get the verified host origin of an Office add-in, so I can remember that the user trusts it for next time? Right now I'm listening for

阅读更多关于 Load document from local filesystem to Office online

I would like to load/save a file directly from the local filesystem in Word online (without uploading it to onedrive). Since this is not part of the default functionality I am trying to determine if this would be possible with an addin. The loading part: The Document object gives access to body load and save Methods however the documentation is unclear (to me) for load: Fills the proxy object created in JavaScript layer with property and object values specified in the parameter. It seems there are options available like insertFileFromBase64 and insertOoxml but unclear if those are only in

阅读更多关于 Two-way communication between VSTO add-in and a Task Pane app (JS/HTML)

问题 Is it possible to have a VSTO add-in and a JS/HTML based Task Pane app talk to each other when running inside desktop Office application? The goal would be to bridge capabilities not yet present (or never will be present) in the x-platform Office APIs using VSTO. 回答1: As Evgene mentioned, there is no out-of-the-box functionality for this (though the topic has certainly come up in internal discussions, so I would be very curious to hear your scenario, and particularly how you would handle the
