Corporate Email Archiving, Storage Quotas, and Data Retention Policies

As organizations grow, accumulated email inboxes consume massive cloud storage and present legal discovery liabilities if retention policies are undefined.

1. Automated Immutable Archiving (Vault)

Configure automated eDiscovery vaults (such as Google Vault) that preserve immutable audit copies of emails even if employees delete messages from active inboxes.

2. Storage Tiering & Quota Management

Implement automated archival rules that transition emails older than 2 years into compressed cold storage, preventing expensive inbox quota upgrades.
