How to Export Entourage for Mac 2008 Emails to Gmail
Product
Entourage for Mac 2008, Gmail
Device & OS
macOS
Scenario
Backing up and migrating old, locally stored emails to a modern cloud email service (Gmail) before performing an OS upgrade that renders the legacy application obsolete.
Observed behavior
Entourage 2008 will not launch or function on newer macOS versions like Monterey, trapping local emails unless they are exported and converted first.
Before you start

Ensure you have an external storage drive with enough space to save your Entourage archive, and verify your current Mac can still run Entourage 2008 before initiating any macOS upgrade.

Solution 1Recommended

Exporting to an Entourage Archive and Native Gmail Import

Use this standard method to export your emails directly from Entourage and use Gmail's native import tool if your legacy email account is still active.

This solution works best if you still have active server credentials for your old email account. Gmail requires access to the original server to pull the old emails directly.

1
Select the Target Mailbox

Launch Entourage for Mac 2008 and click to select the specific mailbox or folder you want to back up and export.

2
Export the Archive

Navigate to the top menu, click 'File', then select 'Export'. Choose 'Entourage Archive' as the file type, pick a safe save location (such as an external drive), and save the file.

3
Access Gmail Settings

Log into your Gmail account via a web browser. Click the gear icon in the top right corner, select 'See all settings', and navigate to the 'Accounts and Import' tab.

4
Initiate Import

Click 'Import mail and contacts', enter your old email address in the pop-up window, and follow the prompts to provide your legacy server credentials.

Inactive Accounts: If your original email account is no longer active or you lack the server credentials, Gmail's native import tool will fail. You will need to rely on a third-party conversion method.

Frequently Asked Questions

Why won't Entourage 2008 work on macOS Monterey?

macOS Catalina and later versions (including Monterey) completely dropped support for 32-bit applications. Entourage 2008 is a 32-bit application, meaning it physically cannot run on modern 64-bit macOS operating systems.

Can I import emails to Gmail if my old email provider shut down?

Gmail's built-in import tool requires an active server connection to fetch messages. If the provider is gone, you must export the local emails to a file, convert them to a modern format like .mbox or .pst, and use an IMAP-connected desktop email client to manually upload them to your Gmail account.

What format does Entourage 2008 export in?

Entourage exports local data as an Entourage Archive file, which has an .rge extension. This proprietary format contains your emails, contacts, and calendar items, but is generally only readable by older Mac email clients or specialized conversion tools.

Is there a way to convert .rge files without third-party software?

Yes, if you have access to an older Mac running an OS that supports both Entourage and an older version of Apple Mail, you can import the .rge file directly into Apple Mail. From there, you can export the mailbox as a standard .mbox file, which is widely supported by modern email services.
