  • Hello Will,

    In short - a lot!

    Let's start from the fact that Web add-ins work only in the Exchange environment, so if you have SMTP or IMAP accounts configured in Outlook you will not be able to use web add-ins. VSTO is the only option for this scenario.

    In general, web add-ins are still very limited in their functionality and work in the context of a single item. I see a lot of suggestions on forums that a particular feature is not supported and you should post your suggestion on the https://officespdev.uservoice.com/ platform.

    Well, it depends on your needs - if you need to support multiple platforms like MacOS and etc., you may be interested in implementing a basic functionality which is possible with web add-ins and have a well-suited VSTO add-ins for Windows desktops.
