Hi @Vass, Mag. Claudia ,
1.If the user's license is removed directly, the person sending the email to that user will receive the NDR.
2.If the user's mailbox is converted to a shared mailbox before the license is removed, no NDR will be received and the email will go to the shared mailbox.
3.The shared mailbox can receive emails, see above.
4-6.What do you mean by delete and revoke respectively? If the email can be received then no NDR will be received. For any undeliverable messages, the sender will receive an NDR.
7.Are you referring to forwarding rules? If the license is removed, the user does not have a mailbox and the forwarding rule will not take effect.
