I have a team of staff: 2 admin staff, 6 sales staff and 1 manager.

Which is the best way to set up configure zoho mail so that:

1) When one of my staff is sick, others can check their emails.

2) All admin related emails get delivered to one email address (like when you make a group) but the emails don't sit in your inbox and get your inbox all cluttered up.

3) When a staff member leaves, how do you keep their email history so it is visible to other staff members that might need to go back and check for email communication or attachments.

Please can someone help with their experience.
