To export mailboxes from Exchange Server 2007 to PST, you can use the Export-Mailbox PowerShell cmdlet. However, it’s a complex and time-consuming process that requires Outlook installation and specific permissions. A simpler and more reliable option is using Stellar Converter for EDB. This tool directly extracts mailboxes from offline or hosted EDB files and saves them as PST files. It also allows selective export of mailboxes and items to PST, Office 365, or live Exchange, ensuring a quick, safe, and hassle-free mailbox conversion from Exchange 2007.
