I re-installed a client machine for virus troubles, and now I gonna sync again the e-mails account with the zimbra server using ZCO and Outlook 2003.

The mailbox size is over 8 Gb, and i would to know if there is any manner to use the old local zdb files (files previously saved), to decrease the total sync time (8 Gb had a sync time of about 3 hours).

Thanks to all who will reply
