Publishing of workflow with a email step in CRM 4.0 rollup 6 fails

Question

The error message is:

"An error occurred when the workflow was being created. Try to save the workflow again."

More info:
Running CRM 4.0, with service pack 6 installed. I was able to publish workflows, but the moment I placed a email step on the workflow it did not want to publish, with the above error message.

Answer 1

I found this very usefull post

In there they pointed to add the following lines to the web.config

<authorizedType Assembly="mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Namespace="System.Globalization" TypeName="CultureInfo" Authorized="True"/>

That fixed my problem, and I am now happily publishing workflow rules.
