In Sandbox:- Create a case via 'Email To Case'.

However, when user tries to answer via email(using service cloud console), following error is coming. Strange enough, case can be answered via 'Portal'.

    "The data you were trying to access could not be found. 
It may be due to another user deleting the data or a system error. 
If you know the data is not deleted but cannot access it, please look at our support page."

What can be possible reason?

  • Just a thought - did you remember to disable the "helpful" email thing set by SF when you refresh a sandbox? Go to Setup -> Deliverability and make sure Access level = all email?

Hits me every time ;)

Recently (Spring'13) SF decided to be helpful in the emails area. Every time you refresh a sandbox they set the Email Deliverability to only system emails. You need to flip it in the Setup -> Deliverability (Access level = all email).

Without this the "send an email" button is gone on the Activity History rel. list and all other quirky things happen...
