Transfers are typically very fast. When you first start a transfer it will show as Queued; the average queue time is just a few minutes but during busy periods can be longer. No further action is required on your part and the interface will update as soon as the transfer begins. Once started, the amount of time a transfer will take to complete depends on the amount of data and number of mailboxes to transfer. The average time is around 30 minutes. You’ll receive an email informing you when the transfer is complete.
