These errors appear to have started with the release of Microsoft Dynamics 365 version 9.0.x. The resolution is to modify the DTS connection Run As User.
- See attached instructions for modifying the Run As User.
- Select a CRM integration User rather than the built-in INTEGRATION user.
- Configure the CRM user as an Integration User ("Integration user mode" = yes)
- If the TIBCO Scribe® Insight CRM adapter publisher is configured, you will also need to modify the publisher to use the new Integration User as the Ignore User.
- If you are using Queue-based integrations, check ALL active DTS files to ensure the "Enable Run As User" option is either unchecked or configured correctly.
NOTE: If the Run As User is not required for the integration, you can uncheck the "Enable Run As User" option to resolve the issue.
