In this article, I’ll show you the process I proform the recipient permissions test. Here are the steps below, I’ll test it on a Shared Mailbox
1. Create a new shared Mailbox.
2. Plan to set the permissions below to the following users:
Administrator: Full Access
User One: Full Access, Send As
User Two: Full Access; Send on Behalf
3. Add User One and User Two to the delegation of this shared mailbox using EAC.
4. Add Administrator Full Access Permission using cmdlet
5. Check for results
6. Add Send As permission to User One.
7. Add Send on Behalf permission to User Two.
8. User Three Login OWA, Send a mail to CONTOSO Support.
9. User One are technical support from CONTOSO, he login to OWA, and open another mailbox of shared mailbox CONTOSO Support.
10 As we can see, User One are able to see the E-Mail sent to CONTOSO Support, and now that he has Send As Permission, he’s able to reply the email directly.
11. When User Tnree check for his email, he’ll see the mail from CONTOSO Support.
12. Now let User Two login, and open Shared Mailbox CONTOSO Support.
