When sending messages in email threads have only one disclaimer and be able to create rule to strip additional disclaimers on reply email.
Maybe Anti- disclaimer rule could be created to edit the body of the message to remove company disclaimer on incoming messages.
at this moment the only possibility is to create an exception like this:
"The object or body corresponds to" -> and I copied the text of the first part of the rule, I used about 30 characters
This was verified by Microsoft support who personally replied to me and confirmed the problem.
I hope a simple system-wide rule will be introduced.
