Attachments are stored in My Documents/GroupWise folder

When viewing attachments to messages, the temp files are created in the My Documents/GroupWise folder by default.

Setting the path option in Tools | Options | Environment | File Location | Save, Check out does not control where the temp files are created.

Create the following registry string value:

HKCU\Software\Novell\GroupWise\Client\Files Locations\EditAttachments

Modify the value to any desired location like c:\temp\, close regedit and restart the GroupWise client for the change to take effect.
