But running an on-premises Exchange server isn’t exactly free.Īlthough the Exchange license is complimentary from Microsoft, you still need a license for the OS and any third party antivirus, monitoring, and backup software the server is running. Microsoft recommends that you use a dedicated on-premises Exchange server to manage email attributes in a hybrid setup. If you try to change the attributes in Office 365, you will see something like this: Any change to email attributes must happen locally on the on-prem object, and from there, it gets replicated to Azure/Office 365. With directory synchronization in place, the on-prem user object is authoritative for all user attributes – including mailbox-related user attributes, like proxyAddresses. This is where things get a little complicated. Also, components like ADFS depend on Azure AD Connect. This makes good sense to most, if not all. Keeping your Office 365 accounts in sync with the on-prem user accounts saves you from maintaining dual identities for each user. For example, you probably still need on-premises user accounts to access local resources like file and print. Many organizations will prefer to keep directory synchronization in place. The steps to get rid of on-premises Exchange involves removing it from the mail flow, removing the Service Connection Point from on-premises Exchange, removing inbound and outbound connectors from Exchange Online, etc.įor a complete walk-through of needed steps, jump to the last part of this article – but I highly recommend reading the next section before you do that! Staying in Sync
If you want to break synchronization, you can remove Azure AD Connect and your on-premises Exchange. Now what?įirst, you should ask yourself if you want to continue synchronizing your on-premises AD with Office 365/Azure AD. You migrated all your mailboxes to Office 365 and want to get rid of the last on-premises Exchange server.
