I have a few clarifying questions to ask:
On Windows: Version 2302 Build 16.0.16130.20298) 64-bit It says "Get Add-ins"
On macOS: Outlook 16.71.2
We're doing "Add from URL..." which works fine in Outlook on the web.
Same behavior on both operating systems. It adds the add-in just fine but it goes away as soon as you close the add-in modal.
If you remove it everywhere, then "Add from URL . . . " in the Win32 client, and look for it in OWA does it show up?
It's possible there is something subtle in the manifest that is preventing the clients from parsing it vs. OWA parsing it (slightly different parsers).
After debugging this for a few hours, I found the issue- we had some SVG files under <Resources><bt:Images>....
OWA loads these fine, but Outlook on the desktop silently fails and uninstalls the add-in.
Expected behavior
Sideloading an add-in in Outlook on the desktop should work
Current behavior
I can sideload the add-in in Outlook on the web just fine by choosing "Add from URL..."
When I try the same add-in in the desktop app on macOS or Windows, it looks as though the add-in was properly added and it shows up under "Custom Addins".
However, as soon as you close the "Office Add-ins" pop-up it goes away. Re-opening it by clicking "Get Add-ins", you can see the custom add-in is gone.
