Please kindly understand that the Outlook tag here we mainly focus on general issues about Outlook desktop client, and know very little about developing add-ins. The following is for informational purposes only.
To host the code for your Outlook add-in in Azure, you can refer to the official Microsoft documentation on how to host an Office Add-in on Microsoft Azure. It provides a step-by-step guide, including prerequisites and detailed deployment steps.
Hope this helps!
