Powershell command to view the free space of the mail database
Sometimes you need to see how much free the mailbox database is. For example, if your storage is almost full, it is impossible to expand the disk capacity. What you can do is to ask the user to download the email locally, and then make a quota and so on. And if you use O365, you can also move up. After a lot of trouble, you have to confirm the size of your email database. Just one Powershell command is fine. Remember to execute it in exchange powershell.
