Storage quota exceeded: Google imposes daily quotas when creating calendar and contact items. This error indicates that Google is preventing the creation of contact or calendar items. This problem will more frequently be encountered when migrating mailboxes containing a large number of calendar or contact data.
Wait an hour and resubmit for migration (Google will "reset" your quota).
If this is blocking, and you'd like to proceed with email migration only:
- Edit your mailbox in MigrationWiz.
- Reveal Advanced Options.
- Disable calendar and contact migration (i.e., "Do not migrate calendar/contact items").
- Resubmit for migration.
Once your migration completes, you may want to retry failed items.
