Hi,
After successfully migrating 200 mailboxes using the email migration wizard on exchange online. If I don't click the "complete migration" link at the end, will this keep the on premise exchange 2007 mailboxes and the newly migrated exchange online mailboxes in synch until I transfer over the rest of the mailboxes?
If the answer to the above is yes, how long can the mailboxes be left in this condition before I have to complete the migration and change the MX records?
Thanks,
Gary.
