Why a Zimbra zmmboxmove can result in seemingly missing folders

On Zimbra 7 when if you use zmmboxmove to migrate an account between mail store servers the command will return that the migration was a success except the folders under the mail tab are blank until about 30 minutes after the move. This is the case even with a test account that has only one email.

This is because the mailboxes are getting indexed. You can check on the status of an account and if it's getting index and you can also manually start it.

$ zmprov rim user@domain.com start
status: started

$ zmprov rim user@domain.com status
status: running
progress: numSucceeded=96, numFailed=0, numRemaining=623

$ zmprov rim user@domain.com cancel
status: cancelled
progress: numSucceeded=139, numFailed=0, numRemaining=580
