There are lots of ways a "public group" (email group) can be created. Microsoft Outlook 365 is routing emails to the folder in a rule (ie: Archive" in this example), when any "people" in a "public group" defined in a FROM RULE, replies to any email.
Example:
Suppose the "people or public group" criteria is set to DEPARTMENT. The folder is set to ARCHIVE. DEPARTMENT is a public group. JOHN DOE is a member of the DEPARTMENT public group. When JOHN DOE replies to an email, and comes to the inbox where this FROM RULE is defined, the email goes into the ARCHIVE folder.
Is there a certain way Microsoft expects the public group to be built, so this does not happen? Or how can I build the rule so it only captures emails when the email originates from the public group?
