Google Workspace Email Migration Problems
Migrating email to Google Workspace involves two separate pieces working together: moving existing mailbox data, and redirecting new incoming mail via DNS. Problems usually happen when those two steps are not sequenced carefully.
Common Causes
- DNS (MX records) switched over before mailbox data finished migrating, causing a gap where old mail is stranded.
- Migration tools timing out or skipping folders on very large mailboxes.
- Duplicate mail appearing when both the old and new systems are receiving mail at the same time.
- User accounts not fully provisioned in Workspace before migration starts.
- Calendar and contact data being overlooked in a plan focused only on email.
Safe Troubleshooting Steps
- Inventory what needs to move: mail, contacts, calendar, and any shared mailboxes or aliases.
- Provision all Workspace user accounts before starting data migration.
- Run the mailbox data migration while old MX records are still active, so nothing is missed.
- Only switch MX records to Google Workspace once data migration is complete and verified.
- Keep the old mail host active for a short overlap period in case anything was missed.

Frequently Asked Questions
Will my old emails come with me?
Most migration paths can move historical mail, but the exact scope depends on the migration tool used and access to the old mailbox. It is worth confirming this before switching DNS away from the old host.
How long does a migration usually take?
It depends heavily on mailbox size and count. Small migrations can complete in hours; large ones with many users can take days.
