I'm working on an outlook add-in I can't get event-based activations to work on the web client (but do actually work on the Mac Outlook app). I've been trying to run the examples hosted on github, both outlook-set-signature and outlook-encrypt-attachments provided by the Microsoft team. And add-in is correctly loaded. I can manage to open the sidepanel and follow the instructions, but nothing changes. Trying the same thing using the Outlook client on Mac OS works as expected.
Here are my reproduction steps:
- Visit https://outlook.live.com/calendar/
- New event > Get Add-ins > My Add-ins > "Add Custom Addins" > From URL > Paste "https://officedev.github.io/Office-Add-in-samples/Samples/outlook-encrypt-attachments/manifest.xml"
- Go back to the calendar app > Click on the three dots button > click "Event Activation Example" addin > The sidepanel shows as expected
- Discard the event and create a new one
- Add a new participant to the event and expect a notification / or add any lightweight attachment and expect an automatically generated encrypted version of the attachment
- Nothing happens . According to the docs, a notification message should be shown
This "unresponsiveness" also happens with my own add-in and also in another example provided by the outlook team https://github.com/OfficeDev/Office-Add-in-samples/tree/main/Samples/outlook-set-signature.
BUT, these add-ins do actually work when I use them on my Mac OS Outlook app (OS Version: Ventura). So I'm wondering if there's any limitation for event-based activations for non-365 users using outlook on a web browser.
