Outlook Web Addin - Event handlers

Question

I have a business requirement where there is a need to extend the functionality of outlook. I am exploring Office Web Addins for this requirement.I have following queries.

1. I need to automatically move all incoming email to an external location.Does Office JS API provide handlers to incoming email event?

2. If it possible to define an action with Office JS API , which when triggered can loop through all the current unread emails and perform some action on each email (like move certain emails to a certain external location )

3. Is it possible to append custom headers to a email being composed using Outlook web add-in?

Answer 1

1. No
2. You can use EWS for that
3. No.

If your code only needs to run under the Windows version of Outlook, a COM addin might be a better option.

Answer 2

Unfortunately, it seems not possible to meet your requirements using Outlook Web Addin.
