• Host [Excel, Word, PowerPoint, etc.]: Outlook
• Office version number: Microsoft® Outlook® for Microsoft 365 MSO (Version 2305 Build 16.0.16501.20074) 64-bit

Expected behavior

Outlook web add-in should be open automatically when we send new email.

Current behavior

We have tried Event base activation to open web add-in when sending new email but outlook web add-in is not opened.

Steps to reproduce

We are using https://learn.microsoft.com/en-us/office/dev/add-ins/outlook/smart-alerts-onmessagesend-walkthrough?tabs=xmlmanifest#smart-alerts-feature-behavior-and-scenarios document to activate Event based activation but it is showing soft Alert instead of opening outlook web add-in as below-

Please do needful asap.

Rajnish-Asite Opening taskpane from event based activation is not supported. Can you share the manifest being used here and code snippet of how you are trying to open the add-in.

Rajnish-Asite Hello! Is there any progress on the feature to open add-in programmatically or any new autoOpen features relates to this issue? I'm looking for functionality to autoOpen add-in panel when "OnNewMessageCompose" event is firing. Are you requesting something similar?

Hi Yevhen Fomin (@fomin-grigorich) I need to open web add-in when Launch Event "OnMessageSend" is fired.

As per previous comment of Outlook Add-ins Team - MSFT (@exextoc) right now there is no any functionality supported from which we can open outlook web add-in programmatically. I am also waiting for this feature.

Please also let me know if you get anything update on this.

Thanks.
