imported contacts are not available when creating new email

ZCS 8.0.2 installed, I imported all accounts from the old server running egroupware being that the emails were imported correctly with imapsync. As the contacts were not exported, the export made ​​in the accounts of users generating. Csv for each account. With the. Occurred csv import correctly I think. The emails appear all the contacts, but when I try to use them by creating a new e-mail they are not available. What did I do wrong? Would be missing something else to be able to use these imported contacts.
