In order to export or import mailboxes to PST files the following requirements must be met:
- Export/Import to PST must be run from a 32 bit client machine with Exchange Management Tools installed (Version Exchange 2007 SP1 or later). The 32bit requirement comes from a dependency with the Outlook client.
- Either Outlook 2003 or Outlook 2007 must be installed on the client machine.
The user running the task must be an Exchange Organization Admin or an Exchange Server Admin on the server where the mailbox to export/import lives.
Exporting mailboxes to PST files
The most basic cmdlet to export a mailbox to a PST file is as follows:
PSTFolderPath must be a full path pointing either to a directory or to a (.pst) file. If a directory is specified a PST file named after the mailbox alias will be used as the target of the export. Note that if the PST file already exists the contents of the mailbox will be merged into it.
