For this part of the Dynamics 365 App for Outlook series, let's talk about what is supported.

At the time of this post, I am covering what is currently supported, including the specific features and clients for which they are available.

Here is the link to the Requirements documentation, which is updated and maintained by the product group, if at any time, this documentation becomes out of date.

The most common questions I receive in this area are:

• Does the App for Outlook support Appointment or Contact tracking on the Mobile Outlook App? This is not available. It only supports Received Emails.
• Can I use the App for Outlook in OWA on a mobile device? No, the App for Outlook is not supported on Mobile OWA for any feature.
• Can I track tasks at all with the App for Outlook? No, tracking of Tasks is currently not available for the App for Outlook on any client
• Why can't I access the add-in from OWA to track Contacts? Contact tracking is not currently available in OWA

Supported browsers for Outlook on the web (OWA)

You can use the Dynamics 365 App for Outlook with Outlook on the web on the following browsers:

• Internet Explorer 11, or Microsoft Edge
  The following configuration is supported:
  • Protected Mode is enabled for Internet security zone. To enable Protected Mode: in IE 11, go to Tools > Internet options > Security tab > Internet.
  • Protected Mode is enabled for Local intranet security zone. To enable Protected Mode: in IE 11, go to Tools > Internet options > Security tab > Local Internet.
  • Your Dynamics 365 URL is in the Local intranet security zone list of trusted websites. In IE 11, go to Tools > Internet options > Security tab > Local intranet > Sites > Advanced.
• Google Chrome (latest version) on Windows
• Firefox (latest version) on Window
• Apple Safari (version 9 or version 10) on Mac or on OSX

An important section to call out from the requirements link is the following section:

If you drill into this, you will find the following:

Internet Explorer 11 or later, which must be installed but doesn't have to be the default browser. To support Office Add-ins, the Office client that acts as host uses browser components that are part of Internet Explorer 11 or later.

What exactly does this mean? - This means that due to the Office Add-in dependency, the App for Outlook only renders in Internet Explorer 11.

If your organization is looking to update your JavaScript libraries and web resources in Dynamics 365 to start using the latest JavaScript language syntax (currently ECMA6), your custom JavaScript may fail through App for Outlook. A transpiler, such as Babel or Typescript, should be used to allow this to work with IE 11 through the App for Outlook.

Another important piece to call out from the supportability and requirements documentation is the following:

What does this mean? - The App for Outlook is not supported and will not work if Oauth is disabled in Exchange Online. OWA does not use Oauth, so you may see the App for Outlook connect there. However, if you try to connect from the Outlook desktop application, this will fail to connect to Exchange. In the diagram below, OfficeJS is what handles Oauth to Exchange Online. (Just a reminder, this blog series is focusing on Dynamics 365 Online/Exchange Online configuration)

Thanks for reading and stay tuned for part 3!
