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 fetch all icons and iFrame HTML from a web-server hosted on AWS. I have attached the manifest down below (sans all ID information, and any other info I deemed sensitive)

A couple of notes

1. The system does not reject my add-in. I see the add-in successfully loaded in the custom section of the store in Outlook Desktop. It only disappears once I close this window.

2. The add-in works on Outlook.com. Passed all QA tests.

3. I assume the add-in is being hard-deleted by the app for some reason? If there is a way to troubleshoot these issues from Outlook, I would love to know. This is my first outlook application (generally a mobile developer).

4. The same issue happens for Outlook for Mac Desktop as it does Outlook for PC Desktop.

Please help!

回答1:

It seems the issue was in the v1_1 version override on the bottom. After I deleted that, I was able to correct the problem

回答2:

Your manifest only has the WebApplicationInfo node in VerisonOverrides 1.1. If the client supports VerisonOverrides 1.1, we pick everything under 1.1 and nothing under 1.0 is used to show on the client. If you need the MessageComposeCommandSurface, you will need to copy everything under VersionOverrides 1.0 to 1.1 as well. This way clients that support VerisonOverrides 1.1, will render the command surface and webapplicationinfo node and clients that do not support VersionOverrides 1.1 will fallback to 1.0 to only show the compose command surface. The fact that it works in OWA is something we will investigate. For now to get around the issue, simply copy everything in VersionOverride 1.0 to 1.1 and you should see things work.
