Hi,
I am facing the Issue Regarding the duplicate activities that has been created automatically while I have checked all workflows and ms flows at my end that may causes this reason but I did not find any thing related to this automatically creating activities, In these activities Subject is same as the original activity from which the duplicate is generated but the Call To field is empty and start date is From 12:00.
Based on the details you have provided, it is possible that plugins are triggering the creation of activities. I recommend checking which actions or table record creations are generating these activities.
1) You can register a plugin on the "Create" message of the Phone Call activity and throw an error. Ensure the plugin is registered as synchronous to analyze which process is failing. This will help identify the specific process or business workflow encountering issues, allowing you to trace the source—whether it's a workflow, plugin, integration, or .NET code.
Sample plugin code
2) Additionally, the Phone Call activity might be created through a custom integration from an external application. For instance, if a phone call is received via an external CTI system, it may be triggering the creation of this activity in CRM. Step #1 will assist in identifying this scenario, as it will generate failure logs or process failures within the external or custom integration code.
You've done the right thing by checking workflows and Power Automate flows, but since you haven't found the culprit there, let's explore other potential causes for these duplicate activities in Dynamics 365:
1. Plugins:
2. Business Rules:
3. Integrations:
4. Server-Side Synchronization:
5. Recurring Activities (Unlikely, but check):
6. Asynchronous Jobs/Workflows:
7. Auditing (To Find the Source):
8. Debugging Tips:
9. Contact Microsoft Support (If All Else Fails):
