3. $Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic -AllowRedirection
4. Import-PSSession $Session -DisableNameChecking
5. Get-MailboxolderPermission “Email Address”
6. Get-MailboxFolderPermission
