How to sync contacts to Outlook in SugarCRM 7.7.1.1?

Since we are using SugarCRM 7.7 we are not able to set the sync to outlook attribute when doing a massupdate. Only thing I can see is that sugar create entries in the contacts_users table, but all but one entries have set deleted=1. So there is only one contact which gets synched to Outlook.

Any ideas?
