We know that sometimes you need to close mailboxes, and still want
to retain the data within those mailboxes in a usable, accessible
format, if needed. We try to make this easy and inexpensive for you, by
reducing the charges by as much as 80% on accounts (mailboxes) you
identify as closed.
If you set any of your mailboxes to the status "closed", which you
can do through your Zimbra domain admin, your user will not longer have
access to the mailbox, and you will only be charged $2 monthly, instead
of your applicable account charge (ie, $5), plus the actual storage in
GB, not the Quota. If active, closed accounts are no longer charged for
Zimbra Mobile.
