When using OnPremise 8.2, when creating an email from dynamics by copy and paste more than one email address brings up all different contacts associated to the email addresses.

Where as in Dynamics online, when creating an email, if we copy and paste more than one email address then all the email addresses are merging and shown as text instead of being picked up as different contacts like in OnPremise 8.2.

Ask:

Is there a possibility to roll back the same feature in Dynamics online organizations as this is taking too much time to copy paste each contact in the TO list or CC list incase of multiple recipients (more than 20 or 30).
