I have an SBS 2008, with about 60 email boxes about 20 onsite and 40 in the field with air cards. We are moving to Office 365. My issue is the bandwidth at the server is very slow, it is over a microwave connections. Download speed is 1.0 and upload is about half that. We are looking at using Quest software for the migration. My question is what is the best route to do all this?
Should I just setup Office 365, change over MX records, give users a shortcut to Office 365 OWA, and synch the mailbox's with Quest. When each one is done let that user know to stop using OWA and go back to Outlook?
Create the Office 365 temp domain, sync all boxes in the background, when done, change Office 365 to FQDN, update Outlook?
Or if anyone has a better suggestion I am listening.
