Why choose a Exchange Hybrid?

Why choose a Exchange Hybrid?

Why a Exchange Hybrid?

  • A Hybrid Exchange environment allows you to take your local environment and the cloud environment together as a single mail organisation.
  • This is practical because the management is on-premise (Active Directory) and the mailbox management can easily be done via a hybrid environment towards Office 365 Exchange Online.
  • Hybrid = Recipient management on-premise, ACL (rights) on-line.

The main advantages of a Hybrid Exchange

  • Hybrid exchange enables secure email routing between your local and Exchange Online organisations. This is not easy with an SMTP gateway.
  • Administrators can use powerful and familiar Exchange management tools to move users to Exchange Online and manage users.
  • Printers using the Exchange environment today continue to relay in exactly the same way as before.
  • Hybrid Exchange is a requirement to migrate as easily as possible without user impact and reconfiguration of each device. With a hybrid migration, only a username & password need be entered after the mailbox move.

Why not choose a hybrid Exchange?

  • If you want to migrate quickly to Exchange Online .
  • If Security is highly regarded in your organisation.
  • If you have no knowledge of Exchange.

Don't you want a Hybrid Exchange?

1. Adjust your mail flow

  • Migrate all mail flow from on-premise to Office 365. So all scanners, copiers, applications dedicated to Office 365.

2. Send your mail via SMTP authentication (recommended)

  • You want to send email from a third-party hosted application, service or device.
  • You want to send e-mail to people inside and outside your organisation.
  • Let your device authenticate directly to the Office 365 mailbox and send out your mails via SMTP auth submission.
  • Benefit: Total control of the mail flow & insight into the mailbox.
  • Disadvantage: There is a licence for each user mailbox.

There are also 2 other methods, which are only recommended if the above options are not sufficient.

  • Option 2: Send your mails directly to O365 over port 25.
  • It is best to take this option only if option 1 is not possible.
  • Option 3: Configure a connector to send mail to Office 365. (relay)
  • It is best to take this option only if options 1 and 2 are not possible.
  • Technical content & configuration can be read here!

3. Decrease your Hybrid Exchange

  • Remove the roles from your Exchange servers so that there are no longer any active roles.
  • Remember that if you just break down your Exchange and use Azure AD connect in Hybrid Mode you always have to manually put e-mail addresses, policies, and so on on the AD objects. This takes a lot more time and does not guarantee typing errors, etc.

4. Recommended Exchange Hybrid only management, no hybrid mailflow.

  • If you still want to do the administration, you can install a Exchange 2016 server with a free licence. (For Exchange)
  • The key can be obtained at: https://aka.ms/hybridkey
  • Unfortunately, this is not (yet) the case for Exchange 2019. It is 2016.
