Hi Office 365 Expert,

I am looking for some info regarding the migration from our exchange 2007 to office 365. We have only about 200 mailboxes and only 1 domain. My query is: what will happen to our AD when we migrate the mailboxes to office 365? How the mailboxes could communicate with our in house AD server?

Thanks.

Regards,

Based upon your requirement, I would suggest you following this informative article that covers all the aspects by checking the prerequisites and would be a good start-up for you: http://blogs.technet.com/b/mspfe/archive/2013/10/08/exchange-2007-on-premise-to-hybrid-deployment-with-office365.aspx

You may also follow Exchange Server Deployment Assistance a programmed application by Microsoft which guides you step-wise to accomplish this task more easily: https://technet.microsoft.com/en-us/office/dn756393.aspx

moreover, If you wish you may also check this programmed solution i.e. http://www.exchangemailboxmigration.com/ which allows to migrate from any exchange server to office 365.

Hi Mac,

we are not planning to implement the hybrid. Meaning that the AD will be still on premise, whereby all the exchange server mailboxes will be migrated to Office 365.

please advise what is the best solution for us.

Thanks
