    \nStep 1:<\/strong><\/p>\n

    Go to Recipients \u2013 On the left side of the dashboard, click Recipients to see a list of all available mailboxes.<\/p>\n

    Step 2:<\/strong><\/p>\n

    Pick the Mailbox \u2013 Click on the mailbox you want to move. If you need more than one, select them, click the three dots and choose Export to a PST file.<\/p>\n

    Step 3:<\/strong><\/p>\n

    Choose Where to Save It \u2013 A box will pop up asking for a “UNC path” (like \\\\Server\\Folder\\Name.pst). Make sure that the folder has enough room and that you have permission to save files there.<\/p>\n

    Step 4:<\/strong><\/p>\n

    Select What to Export \u2013 Decide if you want everything or simply specific items like your calendar or contacts. You can also filter by date if you only need new or old emails.<\/p>\n

    Step 5:<\/strong><\/p>\n

    Start the Process \u2013 Then, click Next to begin. You can check how it is going under the Mail Flow section in the Export Requests tab.<\/p>\n<\/ol>\n

    Exporting through the web interface has some limits. It can be very slow for large mailboxes and the progress bar is not very detailed. You might need to use professional tools instead of this built-in tool.<\/p>\n

      Give Yourself Permission \u2013 Before you start, you must make sure that your account is allowed to export data. Run this command: New-ManagementRoleAssignment -Role “Mailbox Import Export” -User “YourUsername”<\/p>\n

      Step 3:<\/strong><\/p>\n

      Start the Export \u2013 Use this command to begin moving a mailbox to a specific folder: New-MailboxExportRequest -Mailbox “UserMailbox” -FilePath “\\\\Server\\Share\\UserMailbox.pst”<\/p>\n

      Step 4:<\/strong><\/p>\n

      Check Progress \u2013 Since there is no progress bar, use this command to see how much of the export is finished: Get-MailboxExportRequest | Get-MailboxExportRequestStatistics<\/p>\n

      Step 5:<\/strong><\/p>\n

      Clean Up \u2013 Once the status shows as “Completed,” remove the request from the system’s memory: Remove-MailboxExportRequest -Identity “UserMailbox\\MailboxExport”.<\/p>\n
