Just to preface, i know this is technically not the correct way to create Shared mailboxes but it is how its currently done in my company.

Our service desk creates shared mailboxes by creating an Office 365 mailbox on-prem and once in EXO it gets converted to a shared mailbox. What I have found though is that the mailbox will appear directly in EXO without a license and in some cases I have found that when they forget to convert the mailbox to shared it somehow stays in EXO as a user mailbox and continues to work even after 30 days without a license. Has anyone ever seen this? I have no idea how these mailboxes are working.

Thanks!

Is it actually possibly to get a list of all sites and their owners (not admins) using SharePoint / PnP powershell commands without having access to every single site? I feel like I look at this every couple of years but can never find an answer.

Thanks!
