I am assuming that you are trying to transfer from GroupWise to Outlook! Try out the following steps: Install the GroupWise Client. 1. Install the Outlook Client 2. Load GroupWise Client and login as the user. 3. Launch Outlook (this will connect to the GroupWise account that you are currently logged into). 4. Close the GroupWise client. 5. From the File menu select Import and Export. 6. Select Export to a file. 7. Select Personal Folder File (.pst) 8. Select the folder that you wish to export (you may also export sub folders and use the advanced filters) then select next. 9. The last screen allows you to specify the file name and path for the PST file. 10. Click Finish. NOTE: You need to run mail server software somewhere on your network. The mail server must provide either POP3 or IMP support for OE clients to read mail and SMTP support for OE clients to send.
There are some third party applications also available in the market to migrate/export data from GroupWise to Exchange Server. One such popular tool that worked in our case in successful migration from GW 12.0 to Exchange 2013 server: http://goo.gl/abKAm1
Hope this will be helpful to all GroupWise users who want to migrate data from GroupWise to MS Exchange Server/MS Outlook applications.
