Migration to Exchange online RRS feed

  • Question

  • Hi

    Exchange 2010 as part of SBS 2011.

    We are looking at migration to Exchange online with minimum disruption. 

    We should be able to keep our existing accounts in Outlooks with on premises Exchange 2010 while adding the new Exchange online connections? In that case we can just export Emails/Contacts from Exchange 2010 accounts to Exchange online accounts within Outlook and it should work?

  • Hi,

    It’s recommended to use Hybrid. Microsoft Office 365 hybrid migrations provide rich coexistence between an on-premises Exchange environment and Office 365 such as mail routing, calendar and free/busy information and mailbox delegation. It provides organisations the ability to slowly move individual mailboxes to the Office 365 whilst keeping the rich collaboration experience provided by Microsoft Exchange between on-premises and cloud users.

    One of the things that Hybrid provides, is the ability to move the mailboxes back and forth between on-prem and Office365. As well it provides the best available control over users provisioned from on-prem through AADConnect. Note the important thing: Only Hybrid allows the most convenient, flexible and seamless configuration between two organizations, on-prem and Office365 for the end-user. Only Hybrid allows you to revert everything back to the original config and bring your users back on-prem much, much more easily than Cutover.
