CRM 2011 Rollup 10 What are you doing my friend…

Update: On the 17^th of October 2012 Microsoft released Rollup 11 (with a re-release of the outlook client) which addresses this issue. You can download it from the link below.

In August rollup 10 was released for Dynamics CRM 2011, this had a number of breaking changes, here are few of them:

• Issues with saved queries
• Javacript editor character limit
• Issues with Outlook (memory leaks, issue with SQL CE 4, random “an error has occurred”)
• Generic SQL error with quick find
• Microsoft.Xrm.Sdk IsQuickFindFilterIssue (caused ADXStudio portals to break)

About a week ago version 2 of rollup 10 was released, this unfortunately has another side effect. If you configure Claims/IFD and you have old CRM 4 plugins that were upgraded to CRM 2011 they will stop working with the above “The request failed with HTTP status 404: Not found” error. In the event viewer you’ll see a similar error to the one below:

The Web Service plug-in failed in OrganizationId: 010c9151-dbf0-4695-af40-96bcc0fa09f6; SdkMessageProcessingStepId: ad5c7b04-1b4c-4e74-a88b-855302de3b39; EntityName: account; Stage: 50; MessageName: Update; AssemblyName: CRM4.Plugin, CRM4.Plugin, Version=6.3.0.0, Culture=neutral, PublicKeyToken=e86f6c07b0fe8025; ClassName: CRM4.Plugin; Exception: Unhandled Exception: System.Net.WebException: The request failed with HTTP status 404: Not Found.

There are couple of ways around this issue.

1. Stay with Rollup 8
2. Turn off IFD and Claims (keep the HTTPS binding so at least the internal URL will continue to work)
3. Un-register/disable existing CRM 4 plugins and re-write them for CRM 2011
