As a precaution against mistakenly deleting multiple entries unintentionally, Yahoo! Autosync will occasionally ask for confirmation from you. You’ll see a window pop up saying “Confirm deletes for Contacts”. Did you intend to delete all these entries? If not (thank you, Yahoo! Autosync!!!), you have the option to restore them instead of deleting them. Just click the check box next to “Wait! Don’t delete any entries. I want to restore them”, then OK.

If you click OK without first clicking the check box next to “Restore”, the deletes will proceed. If you click Cancel, then Yahoo! Autosync will prompt you again the next time it tries to sync.
