Mailbox size refers to the maximum amount of storage space allocated for an email account. Regularly checking mailbox size ensures that an account doesn’t exceed its storage limit, preventing undelivered emails.
Monitoring mailbox size is essential to maintain a functional email account. When an account reaches its storage limit, new incoming emails may be rejected, leading to missed communications and potential business disruptions. Regularly checking mailbox size allows users to proactively manage their email storage, preventing this issue.
