Users migrating from Gmail to Outlook or Microsoft 365 find that some emails are still being delivered to their old Gmail inbox, despite having updated their DNS and SPF records.

How to Fix Emails Still Going to Gmail After Migrating to Outlook

Product: Outlook / Gmail
Device & OS: not provided
Scenario: Finalizing an email migration from Google Workspace/Gmail to Microsoft Outlook.
Observed behavior: While most messages route correctly to Outlook, certain emails continue to arrive in the Gmail inbox.

Before you start

Verify that your domain's MX records have fully propagated (which can take up to 48 hours) and ensure you have administrative access to both your Google Workspace and Microsoft 365 environments.

Solution 1Recommended

Check Gmail Forwarding, Filters, and Labels

Ensure that old Gmail configurations are not catching, retaining, or redirecting messages before they can be routed to Outlook.

Even after changing MX records, specific configurations within Gmail can intercept emails. This is especially common if you previously set up rules to organize newsletters, notifications, or specific senders.

Access Gmail Settings

Log into your old Gmail account, click the gear icon in the top right corner, and select 'See all settings'.

Review Forwarding Settings

Navigate to the 'Forwarding and POP/IMAP' tab. Check if there are any active forwarding addresses pointing to the wrong location and disable them if necessary.

Inspect Filters and Blocked Addresses

Click on the 'Filters and Blocked Addresses' tab. Look for any active filters that might be archiving emails, applying labels, or redirecting them internally, and delete the ones no longer needed.

Check Gmail Forwarding, Filters, and Labels

Legacy Rules: If you had third-party apps integrated with Gmail for newsletters or notifications, check those applications to ensure they are pointing to your new Outlook credentials.

Solution 2

Analyze Message Headers for Internal Routing

Identify if the emails going to Gmail are originating from other Google Workspace users.

Frequently Asked Questions

How long does it take for MX record changes to fully take effect?

MX record updates typically propagate across the internet within a few hours, but it can take up to 48 hours for global servers to recognize the change. During this transition period, some emails may still route to your old Gmail inbox.

Why do emails from specific senders only go to Gmail?

If the sender is using Google Workspace (formerly G Suite), Google's internal servers may attempt to deliver the email locally to your old Google account before checking the updated public MX records. This is a common internal routing behavior.

Should I delete my Gmail account immediately after migrating to Outlook?

It is not recommended to delete your Gmail account immediately. Keep it active for a few weeks to monitor for straggling emails, ensure internal routing issues are resolved, and update services tied to that specific address.
