If the default email filing folder is defined for an iManage Work Server and the same exists in a workspace, you can select the required workspace and drag the email into this default folder. For more information about configuring the option, refer to the Default Email Folder section in iManage Work Server Administration Guide. Alternatively, navigate and drill down the hierarchy of folders and subfolders and drag the email to the required location.
NOTE: Dragging emails into workspaces isn't supported and an error message appears when you try to drag emails at the workspace level.
