Hi,Does anyone knows how to get a list of shared mailboxes and members with powershell?Thanks in advance,Regards

Here is the powershell to get this Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize:Unlimited | Get-MailboxPermission | select identity,user,accessrights | where { ($_.User -like '*@*') }

thanks it worked.Get-RecipientPermission -Identity "mailbox" -AccessRights sendas | where {($_.trustee -like '*@*') }

The following should work for you: Get-Mailbox -Filter {recipienttypedetails -eq "SharedMailbox"}

Shared mailboxes don't have "members", perhaps you mean a report of users that have been granted Full Access permissions to the shared mailbox? If so, try this script: https://gallery.technet.microsoft.com/Office-365-Mailbox-c2adf0db?redir=0

You can see sendas permissions using the Get-RecipientPermission cmdlet.

Carlos Yohn Zubiría can use the following command.
Get-Mailbox -RecipientTypeDetails SharedMailbox -ResultSize:Unlimited | Get-MailboxPermission |Select-Object Identity,User,AccessRights
it will show the shared mailbox, user who have the permission and the permission level

  Paris Wells Just wanted to say thank you! This worked perfectly. Piped it to Export-CSV, turned that into an XLSX and off to management it goes for review.
  
  Thanks!
