Troubleshooting and things to know about Microsoft Dynamics CRM for Outlook


Applies To: Dynamics CRM 2016, Dynamics CRM Online

This section describes how to troubleshoot Dynamics CRM for Outlook installation and upgrade issues.


If you encounter an issue installing, connecting, or enabling Dynamics CRM for Outlook with your CRM Online organization, use the Microsoft Support and Recovery Assistant to diagnose and fix the issue. You’ll need to sign in to the diagnostics tool with your CRM Online credentials.

Consider the following scenario:

  • In Outlook, User 1 assigns Outlook task to User 2.

  • In Outlook, User 2 accepts and tracks the task.

  • In CRM, User 2 opens the task and makes a change such as changing the subject or marking the task complete.

Result: for User 1, in Outlook, the task status remains unchanged.

To force a status change: User 2, in Outlook, can open the Outlook task and click Send Status Report to update User 1’s Outlook with the latest information.

Enabling the following settings in Outlook Task options (Home tab > New Items > Task > Assign Task) do not impact this issue:

  • Keep an updated copy of this task on my task list.

  • Send me a status report when this task is complete.

This is a known issue and is not supported.
