Exporting Office 365 mailboxes to PST from the Admin Center can be complicated because Microsoft requires admin permissions and eDiscovery/Purview-based export processes for mailbox extraction. A simpler approach is to use the Advik Office 365 Backup Tool , which allows administrators to export PST from Office 365 admin center. The tool preserves mailbox folder hierarchy and exports emails along with important attributes such as attachments, sender/receiver details, timestamps, and email formatting. It also supports exporting multiple Office 365 mailboxes in bulk, making it suitable for organizations that need a faster backup solution.
- Download and launch the Advik Office 365 Backup Tool on your Windows system.
- Enter Office 365 admin credentials and select the option to log in as an administrator.
- The software will load all available Office 365 mailboxes associated with your account.
- Select the mailbox folders that you want to export, such as Inbox, Sent Items, Drafts, Contacts, Calendar, or other folders.
- Choose PST as the export format from the available saving options.
- Apply advanced filters if required, such as selecting emails by date range, specific folders, or other criteria.
