To migrate GroupWise emails to Outlook manually, you can use the following steps:
Open GroupWise and select the emails that you want to export to Outlook.
Save the selected emails as .eml files to a folder on your computer.
Open Microsoft Outlook and create a new folder in your account where you want to import the GroupWise emails.
Select "File" from the Outlook menu and click on "Open & Export".
Select "Import/Export" and then choose "Import Internet Mail and Addresses".
Select "Microsoft Exchange" as the email server type and click "Next".
Click on "Import Internet Mail and Addresses" again and select "Personal Folder File (.pst)".
Choose the option "Import items into the same folder in:" and select the folder that you created in step 3.
Click on "Next" and then select "Finish" to start the import process.
Outlook will begin importing the .eml files into the selected folder. The process may take several minutes, depending on the size of the files.
Once the import process is complete, you should see all of the GroupWise emails in the selected folder in Outlook.
