Please help in providing the steps to covert all unknown Mimetype documents to text/plain. I did the following steps but it is not getting updated. Please help if i am missing anything.
You cannot use a rule to set the CMIS contentStreamMimetype pseudo property. This property does not actually exist - it has only been defined to support the CMIS interface integration. Instead of using the "Set property value" action you should use the "Change/Set mimetype" action instead.
Also note that for *.msg files the mimetype text/plain is certainly not the correct mimetype, and Alfresco will not be able to properly display such emails nor index them correctly.
Thanks for your reply, but unable to find such a option "Change/Set Mimetype" action. I am able to see only the below options. Please suggest if we need to activate anything to get this option.
Sure will try that, I have not created any script till now.
Can you please guide me with the exact parameter which is related to Mimetype, will try updating it. Thanks in advance.
Check ScriptNode API for details. The simplest possible script would just be a single line:
document.properties.content.mimetype = 'text/plain';
