CRM 2011 - Attach emails to Opportunity error - WRPC Token

Question

G'day All,
I have a strange issue with emails being attached to opportunities, it randomly fails but if you try to track it again, you get a message stating the email is already tracked. I have walked through the process and cannot find a direct cause except in the events
log I get these exception errors.
Event code: 3005

In most of the articles it suggests to enter a registry key to disable the token checking, but I am not sure what the knock on effect of this will be if I disable the token check. But more importantly, I am concerned about what may be causing this in the first
place.
The emails that are being attached, can be quite large, as a lot of them are plans (2-5mgs) but in the grand scheme of things they are not that big at all.
Any help, pointers, thoughts, will be gratefully accepted.
cheers
Jamie

You would get this error if the custom workflow assembly is registered in the Sandbox. Try reregistering the assembly so that it is not in the sandbox
