The document outlines the process and considerations for deploying Exchange 2013 in hybrid mode using Netgains Technologies' Officeconnect. Key topics include setting up hybrid configurations, prerequisites, deployment processes, and common issues. The document emphasizes the importance of proper configuration for seamless mailbox migration and integration between different email systems.

Hybrid Mode

2. Building a hybrid configuration
Expectations… Reality (Ex2013)…

3. What is a hybrid deployment?
Exchange
On premise
“Virtual Exchange-OfficeConnect Organization”
“The
Internet”/”Corporate
Network”
NetGains
OfficeConnect

4. Why hybrid?
• Long-term coexistence
• Take advantages of Affordable NetGains OfficeConnect
• Large migrations where cutover is not possible (e.g. EX2010 +)
• Two companies merge but maintain separate systems for a period of time
• Non-Exchange systems are involved in the email environment, eg a Unix
qmail server
• Adapt newer email systems and features with upgrade.

6. First Step towards setting up Hybrid..
To share the namespace we simply change the DomainType to InternalRelay

7. Hybrid Configuration – Send Connector
• Secanpda Cbiolitniensector to tell Exchange where to send the emails that do not
have a local recipient.
• IP address of the other email system is configured and the Hub Transport
server is used to send the emails
• Now when an email arrives on the Exchange server that has no matching
local recipient address, it will forward it on to the other mail system for
delivery.

8. NetGains OfficeConnect Configuration..
• Mails received from Exchange Send Connector are delivered locally.
• Mails generated locally with recipient's on Exchange will be forwarded to
MX of the domain.
• Mails rejected by Exchange Server for not having local mailbox are
bounced back to Sender.
• Detailed SMTP in/Out Logging.

9. Hybrid Prerequisites
• A Windows Server Running NetGains OfficeConnect.
• OfficeConnect Exchange Connector.
• Exchange Server with Domain Relay type set to Internal Relay.
• MailBox naming conventions to avoid duplicate mailbox on Exchange and
OfficeConnect Server
• Administrative access to both OS and Mail Servers.

13. Deployment Considerations
• Delegates
• Mailbox creation, deletion, Password change need to be handled by respective mail
server administrators.
• Mailbox Permissions
• Mailbox ownership, access rights, Access locations need to be defined for
OfficeConnect.
• Multi-forest scenarios are not supported
• Interaction with legacy / 3rd party applications
• Web Services?
• Use an SMTP gateway?
• Bandwidth

14. Hybrid mailbox moves
Exchange

“The Internet”
OfficeConnect

MRS – Mailbox replication service.

16. Mailbox moves: user experience
• When a mailbox is moved based email client user experience defers..
 Microsoft Outlook users will continue to use same interface.
 OWA users will see all the new interface with lot of similarity to Outlook 2010.
 eMail password can remain same or changed based on policy.
 Mobile users can use local client or OfficeConnect web Interface.

17. Common mistakes/issues
• Certificates
• Expired
• Not from a trusted source
• Missing/Wrong subject (alternative) name
• Delay in mail delivery from OfficeConnect to Exchange if the MX is very
Busy.
• OfficeConnect SMTP IP and Exchange SMTP should be whitelisted.
• Users not recognized as “internal” if domain type in not changed
• Outlook-related (e.g. missing updates)

18. Troubleshooting
• Hybrid Configuration Log Files
• OfficeConnect maintains SMTP logs of all the mails it receives and sent to external
world and Exchange.
• Firewall, IPs and Ports
• Ips of both SMTP Server for Exchange and OfficeConnect should be whitelisted and
logs are maintained.
• Review OrganizationRelationShips
• Get-OrganizationRelationShip | fl *
• Troubleshoot connection issues (e.g. AutoDiscover/Web Services)
• Remote Connectivity Analyzer (www.testexchangeconnectivity.com)

20. Key takeaways
Mind the prerequisites!
Use tools like ExDeploy and remote connectivity analyzer
to plan and validate your deployment
Review the hybrid configuration logs for more
information.
