Example works only in OWA

[Wh4teverr]

I implemented the plugin via ECP and everything works properly in the WEB version.

However, in the classic version of Outlook, the plug-in starts, but the javascript does not work, it seems that the Office.onReady method never executes. Do you know what is the reason for this?

Hi @Wh4teverr,

Thanks for reporting this issue. However, could you please specify to which sample you are referring?

[Wh4teverr]

Yes, of course. I am referring to outlook-hello-world sample.

I mean: https://github.com/OfficeDev/Office-Add-in-samples/tree/main/Samples/hello-world/outlook-hello-world

Thanks for providing the sample, @Wh4teverr. When you get a chance, could you provide the version and channel of your classic Outlook on Windows client? And to clarify, when you say you implemented the add-in via ECP, are you referring to this deployment method: Deploy add-ins in the Microsoft 365 admin center?

I tested locally installing the manifest and also deploying it via the Microsoft 365 admin center and confirmed that the add-in runs as expected in both Outlook on the web and on Windows (classic and new). If you locally install the manifest, does the add-in work in your Outlook desktop client?
