Hi, Mic
You can try either manual process (only applicable with Outlook 2002, Outlook 2003, and Outlook 2007 ) or third party tools to easily export Exchange Server Offline (OST) mailbox into Outlook.
Manual process does not support Outlook (2010, 2016, 2013) to export Exchange Server Offline mailbox into Outlook.
  1. On the File tab, click Open, and then click Import.
  2. Select Import from another program or file, and then click Next.
  3. Select Outlook data file (.pst), and then click Next.
  4. Click Browse, and then locate the PST file that you exported.
  5. Select Do not import duplicates, and then click Next.
  6. Under Select destination folder, click a folder to which you want to import the information, and then click Next.
  7. Click Finish.


Third Party Tools - OST Recovery is third party tools that supports all editions of MS Outlook including Outlook (2016, 2013 & 2010 with older version too.) and allows to export emails from Offline Exchange Server into Outlook successfully.


Thanks & Regards
