Outlook Event Based Add In Not Running When Drafting Offline But Sending Online

[Buxt-Codes]

Hi all!

I'm a developer of an outlook add in that's event based and uses OnMessageSend event activation. However, users noticed that if they were to start a new draft while Wi-Fi is off and then subsequently turn it back on before sending the email, the add in will run but will show that it is taking longer than expected to load. I checked DevTools as its webview based and checked the network tab. But I could not find any discrepancy in the difference between starting a draft offline as compared to while online. Furthermore, I noted that when the add in says that it's taking longer to load, there was no network call to my outlook add in resources unlike if the email was drafted online and sent online as well. This problem only occurs in Outlook (new) and not Outlook (classic). Are there any solutions to this or explanations for this?

Thank you!
