Enerprise Vault: No action taken mailbox disabled

Hi All,

I have critical problem, I have 1390 targeted mailboxes , but each time I run archive task only 316 mailboes are proccesed and remaining 1074 were taken no action. In report I found mailboxes disableted But in actual all mailboxes are enabled 

Could someone will guide me how may I start workaround on this?

Thanks in advance
