Hans,
thank you for your reply. Meanwhile, I've found the settings, they are stored in the registry (HKEY_CURRENT_USER\SOFTWARE\Nokia\Nokia Suite\SyncSettings), but changing by hand them did not help.
I switched back to office2013. There is some other software as well, that doesn't work with the new version, so I have to wait for an update of these programs. Like you, I think, that the Nokia Suite won't be updated any more.
Kind regards
Herbert
