Passing extra parameters to standard CRM forms
Recently i have needed to pass extra parameters between the standard CRM forms (Accounts,Contacts,Activities etc), however there is a filter that is run when the forms are requested to disallow any illegal parameters being passed to them.
Thankfully there is a nice little registry fix to disable this.
Add a new DisableParameterFilter key to HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSCRM” and set the value to 1 (as above)
You will need to run IISRESET for this change to be set.
