What is a mailbox quota?
A mailbox quota defines the maximum storage space a user can consume. Incoming and outgoing messages, attachments, folders and other email data all use this capacity.
What happens when the quota is full?
A completely full mailbox may stop accepting new messages. Senders can receive delivery errors and important business communication may fail to reach the intended employee.
Large attachments consume storage quickly
Departments working with images, PDF documents, quotations or technical files can accumulate large mailboxes rapidly. Repeated copies of the same attachment also increase storage usage.
Set quotas according to user needs
Not every employee requires the same amount of storage. Management, sales or project teams may need more space, while accounts with limited email activity can operate with smaller quotas.
Manage older messages
Deleting unnecessary email, cleaning trash and spam folders and archiving older messages can help organizations keep mailbox usage under control.
Central quota monitoring
A centrally managed business email platform allows administrators to monitor mailbox usage and respond before an account reaches its storage limit.
