Implementing an exchange hybrid environment allows your on-premise Exchange server to work with Office 365 as one single environment. This setup lets you manage both environments as a single unit.
These steps can be followed to incorporate the simple and easy-to-understand method for configuring the hybrid Exchange environment.
Step 1: Prepare Your Environment
As a first step, to be more precise, you have to ensure that your local environment is ready to use. Your Exchange server should be running a supported version. Check Microsoft’s website for the latest requirements. Also, ensure your domain is verified with Office 365. This means you have proved to Microsoft that you own your domain.
Step 2: Install the Hybrid Configuration Wizard
Microsoft provides the Hybrid Configuration Wizard to help set up the hybrid environment. Download and install it from Microsoft’s website. The installation process is straightforward. Follow the prompts to complete the setup.
Step 3: Run the Hybrid Configuration Wizard
After the tool is installed, proceed to Performing Hybrid Configuration Wizard. The wizard will make configuring it easier. Here, you get the prompt that you would have to Log in with your Office 365 admin account. The wizard will then spot your on-premises Exchange server.
Step 4: Configure the Hybrid Environment
The wizard will ask you several questions about configuring the hybrid environment. These include:
- Hybrid Features: Choose the hybrid features you need. You can choose a complete or minimal hybrid configuration. A full hybrid offers more features, like mailbox moves and calendar sharing, while a minimal hybrid offers basic features.
- Domains: Select the domains you want to include in the hybrid environment. When configuring the connectors, these should be the exact domains authenticated with Office 365.
- Mail Flow: Determine what is being exchanged between Office 365 and on-premises servers through mail. Here, the author merely receives information regarding the location of the mail flow, which can be centralized or decentralized.
Step 5: Configure Certificates
Certificates are essential, particularly when developing secure communication between Office 365 and the on-premises Exchange server. A Hybrid Configuration Wizard will appear when configuring an extended access point, requiring you to choose a certificate. Ensure the company obtains this certificate from a known certificate authority (CA). If none is available, it has to be procured from a CA.
Step 6: Update DNS Records
After configuring the hybrid environment, update your DNS records. This step is crucial for mail flow and service discovery. The Hybrid Configuration Wizard provides the DNS records you need to update. Add these records to your DNS hosting provider.
Step 7: Verify the Configuration
Once you have updated the DNS records, verify the configuration. Check if users can access their mailboxes from both environments. Ensure that mail flow works correctly between Office 365 and your on-premises server: test calendar sharing and other features you enabled.
Step 8: Move Mailboxes
With the hybrid environment set up, you can start moving mailboxes to Office 365. Use the Exchange admin centre or PowerShell to move mailboxes. The process is simple and can be done in batches. Ensure users know when their mailboxes will be moved to ensure everything is clear.
Step 9: Monitor and Maintain
After setting up the hybrid environment:
- Monitor it regularly.
- Check for any issues with mail flow, user access, or other features.
- Use the tools provided by Microsoft to maintain the hybrid environment.
- Regular updates and maintenance ensure smooth operation.
Conclusion
Before implementing a hybrid Exchange between Office 365 and On-Premise Exchange, the above steps should be followed. To come up with an excellent hybrid setup, you need to begin by preparing the environment for a hybrid setup, and after this, take your time and run the Hybrid Configuration Wizard, and also take time in configuring the certificate and updating your DNS records. Users can switch between these two environments and perform their actions as one extensive system. Regular monitoring and maintenance will keep your hybrid environment running efficiently.
