Currently we are facing storage issue in the production org. EmailMessage has consumed most of the data storage there. As of now we don't want to store the old data to another storage as client need this data.We are looking for a diff solution for reducing the EmailMessage storage by processing old data. As we are thinking to convert html emails to plain text but this can be processed on new emails not the existing one as we have restrictions from salesforce that we can not perform update operataion on EmailMessage.
Is there any way I can get this working?
Thanks in advance!
