We use CRM 2016 SP1. We deployed our latest changes from Dev to QA, staging and production by means of importing a managed solution file. As part of the solution file there is a custom Action workflow (Category = Action) with the publisher prefix set to our company name.
The workflow has been activated and working well in QA and staging but when trying to activate it on production CRM comes up with the error "Unexpected Error". Downloaded error details show the same message.
Upon investigating the workflow in production we realised that its publisher prefix had been changed to "new_". To be more specific, the Process Name property starts with the correct prefix name but the Unique Name property starts with "new_".
We had not made any changes to the workflow in Dev and it was working fine in production prior to the deployment.
So far my research on the Internet on how/why this change has come about and how to fix it has been in vain. So any help is greatly appreciated. Regards
