Tip: Use the Exchange Management Shell to Determine the Status of Databases

Mailbox and public folder databases have several associated states, including:

  • Mounted
  • Dismounted
  • Backup In Progress
  • Online Maintenance In Progress
  • Replication In Progress

You can determine the status of a database by following these steps:
1. In Exchange Management Console, expand the Server Configuration node, and then select the related Mailbox node.
2. In the details pane, select the Mailbox server you want to examine. You should see a list of storage groups that are available on the server.
3. For each storage group, you should see a list of available databases. The icon to the left of the database name indicates the mount status. If the icon shows a gray down arrow, the database isn’t mounted. Otherwise, the database is mounted.
4. To determine the status of the database, right-click the database, and then select Properties. In the Properties dialog box, the status is listed on the General tab. In the Exchange Management Shell, you can determine the status of all or specific databases using the get-MailboxDatabase and get-PublicFolderDatabase cmdlets.
