What Is the Dynamics 365 App for Outlook?

‍

The Dynamics 365 App for Outlook is a lightweight app installed (pushes the app to users) to outlook users. A system admin can push this app to the user or all the users.

You can use the app from Outlook on the web (OWA), the new Outlook for Windows, the classic Outlook desktop client, and Outlook mobile. It helps users track email to CRM, sync outlook contacts and accounts, and view and interact with CRM data (Accounts, Leads, Contact, Emails etc.).

Dynamics 365 App for Outlook Requirements

‍

Please review specific requirements before you can deploy/use Dynamics 365 App for Outlook.

‍

Security Role: Dynamics 365 App for Outlook User

Ensure that the users have the following security role: Dynamics 365 App for Outlook User.

This is an out-of-the-box that comes shipped with your instance. I would recommend setting this role for the user who wishes to use Dyn 365 App for outlook.

This role gives proper access to have the user use the D365 app for outlook features in their outlook, without running into permission issues. However, depending on your customizations, it's possible that you may need to assign more permissions to the users to prevent permission issues on the Outlook side.

Email Server & Email Configuration

Make sure that your email service is supported and that server-side synchronization is set up for email processing. This is the most common cause of setup problems, so configure it first.

Server-side synchronization runs in the background about every 15 minutes. Items it promotes show a Pending track status until the cycle completes.

You can also integrate on-premises Exchange through a hybrid configuration with Dynamics 365. Click HERE to learn more.

• Exchange Online is the primary supported path.
• On-premises Exchange is supported through a hybrid configuration with a current supported Exchange Server version.

Dynamics 365 Exchange Online Integration - Email Client (Desktop Client)

Alongside the email server, make sure that your Outlook client is supported. Keep your client current. The App for Outlook supports:

• Microsoft 365 Apps for Outlook on the Current, Monthly Enterprise, or Semi-Annual Enterprise channels.
• Outlook on the web (OWA).
• The new Outlook for Windows.
• Outlook for Mac.
• Outlook mobile (iOS and Android), with Exchange Online.
• Older perpetual-license builds reach end of support over time, so run a supported Microsoft 365 Apps version.
