READ ONLY ACCESS IN SHARED MAILBOX WITH POWERSHELL

Όταν θέλουμε να δώσουμε read-only access σε shared mailbox ακολουθούμε τα εξής:

#Αν είναι η πρώτη φορά που τρέχουμε την διαδικασία στον υπολογιστή μας τρέχουμε:
Set-ExecutionPolicy RemoteSigned
#και μετά επιλέγουμε Α
$UserCredential = Get-Credential
#όπου βάζουμε το email και το password
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection

# Ξεκινάμε το session

Import-PSSession $Session

#Στο πεδίο identify βάζουμε το email του mailbox που θέλουμε να έχουμε πρόσβαση. Στο πεδίο user βάζουμε τον χρήστη που θα έχει πρόσβαση στο mailbox

$target_mbox="calendar@enlogic.gr"
$owner="anag@enlogic.gr"
$inbox="Εισερχόμενα" # or "Inbox"
$sent="Απεσταλμένα" # or "Sent"
Add-MailboxFolderPermission -Identity $target_mbox -User $owner -AccessRights Reviewer
Add-MailboxFolderPermission -Identity $target_mbox:\$inbox -User $owner -AccessRights Reviewer
