Outlook for Mac add-in with the newly released office.js API

Question

We have an add-in for Office Apps - using the compose form on Outlook appointments in the calendar.

Because finally the office.js add-ins support for Outlook for Mac is out as written here, I have some questions:

• How can I debug the JS in the add-in side pane in Outlook for Mac? Since the behavior is sometimes different to Outlook Web
• Office.context.mailbox.item.body.setAsync(newBody, { coercionType: Office.CoercionType.Html }, callback) seems to do nothing, only for Office.CoercionType.Text it seems to work
• Is it possible to open a web page in the browser instead of a modal window? Because window.open(url, target, features) opens a modal window on top of the appointment, which is again different behavior to Outlook Web Client
• It looks like JS is much slower in Outlook for Mac

Answer 1

Question #1 MacOutlook uses webkit to render addin page. You can run the following command from CLI

defaults write NSGlobalDomain WebKitDeveloperExtras -bool true

Restart the outlook and invoke the Add-in. You will see new menu item inspect Element which will let you inspect the elements in the page.

Question #3: If the URL to be opened in a domain that is not listed in appmanifest, the URL will be opened in a separate browser window. The url to be opened is in the domain listed in appmainfest, you will see a popup window. MacOutlook uses modal window due to the limitations of webkit library currently being used.

Question #2 : Can you give specific steps to reproduce the problem and share the Outlook version that you are using - We do not see this problem
