Public Folder data can be migrated through Outlook email client. The following instructions apply to Outlook 2010/2013/2016/2019.

  1. Public Folder data from your old Exchange mailbox should be exported into a .PST file. To do that you need to have Outlook connected to your old Exchange server with appropriate permissions for the Public Folder you are going to migrate. The Public Folder in question should be selected in the tree when Outlook asks for the folder to export from. Read the Knowledge Base article on How To Export Data In Outlook for more information.

Note: If the .PST file includes complicated folder structure you may upload it to Outlook Backup via FTP and ask Intermedia support team to import it into Public Folder from server side.

Please do not import the file directly with Outlook import tool as it may cause permissions issues.
