Hello,
One of our user receives a .NET Framework error when doing a "Set Regarding" on an email.
We use CRM 2013 on premise with Update Rollup 1. He has .NET Framework 4 installed on his computer.
What's especially strange is the red crossed squares(see hereunder picture) that prevent us from troubleshooting the issue.
When we upgrade to NET Framework 4.5.1 the problem is sovled but we do not understand why this occurs all of a sudden.
He used the Addon for months without coming accross this issue.
Thanks in advance,
Best regards,
