@ruwi-next you mentioned "Office on the web, PC desktop and Mac" under platforms.
Do you mean that you see this happening in the Windows Outlook client and on the Mac Outlook client (separately from Office on the web)?
If so, can you please provide a video for the Mac and PC Desktop clients as well? The video only shows the web-based outlook but not the clients.

Hi yes, I have attached a video of the same behaviour in the new Outlook Windows Desktop app. Upon retesting it appears this does work correctly on the Outlook Mac Desktop app. As for classic Outlook on Windows we do not target this and so I am not able to test this.

For anyone else running into this issue it can be mitigated by registering the onMessageCompose event. This will initialize your addin before the attachments events are dispatched meaning the bug, what I assume is a race condition with initialising the addin, isn't triggered.

Hi @ruwi-next, we haven't been able to reproduce the issue. Could you please share the manifest you're using when experiencing the issue? This will help us investigate further. It's great to hear that you've found a workaround.
