When an employee leaves your company, a critical question arises: What should you do with their email account? Deleting it can lead to data loss, while keeping the license active costs money. For many businesses, the best answer is to consolidate that mailbox into a central archive account.
This process allows you to retain important data for compliance, legal, or historical needs while freeing up a paid user license. While the task may seem complex, a defined process makes it manageable and safe. This guide walks you through the concepts and steps to perform a Google Workspace mailbox consolidation correctly.
Why Consolidate Google Mailboxes? The Business Benefits
Moving emails from multiple accounts into one central location offers several clear advantages for your business operations.
Cost Savings: De-provision the original user account and stop paying for an unused Google Workspace license.
Data Retention: Keep a complete record of communications for compliance or legal requirements without maintaining a full, active account.
Simplified Access: Provide a single point of access for HR, legal, or management to review historical data when needed.
Improved Security: Centralize archived data in a secure account with limited access instead of having multiple inactive accounts floating around.
Understanding the Method
The most reliable way to perform a mailbox consolidation is to use a command-line tool that communicates directly with Google's APIs. This method provides administrators with precise control over the process. The core logic is built around three key functions that ensure a clean and organized result.
Here is a breakdown of the main command options and what they do for your business.
Command Option | What It Does | Why It’s Important for Business |
--service-account | Uses a special admin account to access data without needing user passwords. | Provides a secure, auditable way to manage company data without compromising individual employee account security. |
--label-restored | Applies a new, specific label to every email moved into the archive. | Keeps the central archive organized. You can easily see which emails came from which person. |
--strip-labels | Removes the old user’s personal labels (e.g., "Projects," "Urgent") from emails. | Prevents clutter in the archive account and keeps the data clean and simple to sort through. |
The Process: A Step-by-Step Guide
Consolidating an account is a two-phase process: first, you create a secure backup of the source mailbox, and second, you restore it to the central archive.
Here is a simplified example of the commands for migrating an employee’s email (k.byrum@beyondcorp.com) to a central archive (migration.archive@beyondcorp.com).
Step 1: Create a Local Backup Folder
First, you need a dedicated folder on your computer to securely store the backup.
mkdir ~/beyondcorp_migration/k_byrum_backup
Step 2: Back Up the Source Mailbox
Next, run the backup command. This tells the tool to use its admin access to copy all emails from the source user into the folder you just created.
# This command restores the backup to the new location with a clean label.
./gyb --email k.byrum@beyondcorp.com --service-account --local-folder ~/beyondcorp_migration/k_byrum_backup/
The tool will show progress as it saves every message.
Step 3: Restore to the Archive Account
Finally, run the restore command. This takes the backup you just made and moves it into the central archive. It also applies your new label and removes the old ones.
# This command restores the backup to the new location with a clean label.
./gyb --email migration.archive@beyondcorp.com --action restore --local-folder ~/beyondcorp_migration/k_byrum_backup/ --label-restored "Migrated/K.Byrum" --strip-labels
Once the process completes, all of the employee's emails will be safely stored and organized in your migration.archive@beyondcorp.com account.
