Powershell command to get a report of a specific shared mailbox

[Arslan11]

I am connecting to Exchange online powershell module, and I need assistance with one thing.

I have got a shared mailbox on exchange online called "Customer Service - Network Homes" and email address of the mailbox is "CustomerService@networkhomes.org.uk".

I need a powershell script, which will show you who has got send as permission to the shared mailbox.  I want to pull out the information from the script instead of looking at the console.

simple cmdlet like one below should do it
Get-RecipientPermission -Identity "CustomerService@networkhomes.org.uk" | Out-File c:/temp/filename.txt
