Empty restored folder randomly on multiple user account !!

Hi, my zimbra server cashed one week ago , i 've restored my virtual (vmware) machine dating form 12/20/2016 and i ' ve launch restoration off all the domains.
But it's appear that some restored folder are empty ?? no message inside. i've try some console command to search message but it was unsuccessful...
I try also to update zetra suite ..
i try to find in the backuped file of zextra if this message exists, but it's hard to says yes or no ...

Have somebody the same problem ?
Is there a way to restore correctly these empty folder ?

Zimbra 8.0.5 / zextra 1.81.12

after investigation zextra 2.2.4
