I need to get the permissions on Shared Mailbox. Usually you would do it using Outlook. This is fine if I need it for a single mailbox. Now my manager has asked me to generate the permissions list for all the shared mailboxes in the Organisation(roughly around 300). I also need to find out what permissions each user has,for ex Owner, Author, etc..
Is there a way to do it without having to use Outlook. Any tools out there..
Any advice would be appreciated.
