Fix email dates broken by IMAP migration

All emails showing the migration date instead of the original? Redate.io restores correct dates automatically.

Works with Google Workspace, Microsoft 365, and any IMAP server

Every email shows the wrong date after migration

After migrating to Google Workspace, Microsoft 365, or another provider, your email client shows the migration date on every message. Outlook, Apple Mail, Thunderbird - they all display the wrong received date. Sorting by date becomes useless.

  • Cannot find emails by date
  • Legal and compliance risks
  • Users complaining to IT about broken dates
  • Sorting by received date is useless

Frequently asked questions about email date fixes

Why do all my emails show the same date after migration?

IMAP migration tools (BitTitan, CloudM, imapsync, GSMMO) add a 'Received' header with the migration timestamp. Email clients like Outlook use this header to display dates, causing every email to show the migration date instead of the original send date.

Can email dates be fixed after migration is complete?

Yes. Redate.io fixes email dates even months or years after the migration. The original date is preserved in the email's 'Date' header and can be restored by removing the migration headers and re-inserting the email with the correct INTERNALDATE.

Is it safe? Will I lose any emails?

Zero data loss is guaranteed. Redate verifies every fixed email against the original before completing the process. Original emails are kept in a visible folder for 30 days, allowing full rollback at any time.

How long does it take to fix email dates?

Redate processes 500-1,000 emails per minute. A mailbox with 10,000 emails typically takes 10-20 minutes. The initial free scan takes just a few minutes depending on mailbox size.

Why does Outlook show the wrong date after migration?

Outlook displays the date from the most recent 'Received' header, not the original 'Date' header. When a migration tool adds its own 'Received' header, Outlook uses that date. Redate removes these migration headers to restore the correct date.

What causes wrong email dates after IMAP migration?

The IMAP protocol requires a 'Received' header on insertion. Migration tools like BitTitan MigrationWiz, CloudM, and imapsync add this header with the migration timestamp. Email clients then display this timestamp instead of the original date.

How much does fixing email dates cost?

Redate.io charges 0.007 EUR per corrected email, with a minimum of 29 EUR per mailbox. The scan is free. A valid payment card is required before scanning, but no charge is made until the fix is approved.

Do I need admin access to fix email dates?

For Google Workspace and Microsoft 365, admin access is recommended to fix multiple mailboxes efficiently. For individual mailboxes, direct IMAP access with regular email credentials works fine.

What happens to my original emails during the fix?

Original emails are moved to a visible folder called 'Redate.io - Originals' in your mailbox. They are never deleted. You have 30 days to verify the results and can restore originals at any time.

What if the original date is missing from the email headers?

Some emails may lack the original 'Date' header. These are automatically skipped and reported. You only pay for emails that are actually fixed. If no emails can be fixed, Redate offers a full refund.
