Import of Archived/Offline Mail
Migration
IMAP migration (IMAP)
Supports wide range of email platforms
Email only (no calendar, contacts, or tasks)
Cutover Exchange Migration (CEM)
Good for fast, cutover migrations – up to 2,000 mailboxes
No migration tool or computer required on-premises
Staged Exchange Migration (SEM)
Hybrid
No server required on-premises
Identity federation with on-premises directory
Hybrid deployment
Manage users on-premises and online
Enables cross-premises calendaring, smooth migration, and easy off-boarding

Self Service
Admin-Driven
Deployment Type
Description
Federation Trust
• Delegated authentication for on-premises/cloud web services
• Enables Free/Busy, calendar sharing, message tracking, online
archive, and more
Integrated Admin
Experience
• Manage all of your Exchange functions, whether cloud or onpremises from the same place - Exchange Administration
Center (EAC)
Native Mailbox
Move
Secure Mail Flow
• Remote move migration (Online mailbox moves)
• Preserve the Outlook profile and offline file (OST)
• Leverages the Mailbox Replication Service (MRS)
• Authenticated and encrypted mail flow
• Preserves the internal Exchange messages headers
• Support for compliance mail flow scenarios (central transport)
Hybrid Coexistence Feature Comparison
Feature
Simple
Hybrid
Mail routing between on-premises and cloud (recipients on either side)


Mail routing with shared namespace (if desired) on both sides


Unified GAL


Free/Busy and calendar sharing cross-premises

Out of Office understands that cross-premises is “internal” to the organization

Mailtips, messaging tracking, and mailbox search work cross-premises

OWA redirection cross-premise (single OWA URL for both on-premises and cloud)

Single tool to manage cross-premises Exchange functions (including migrations)

Mailbox moves support both onboarding and offboarding

No outlook reconfiguration or OST resync required after mailbox migration

Preserve auth header (ensure internal email is not spam, resolve against GAL, etc.)

Centralized mail flow , ensures that all email routes inbound/outbound via on-prem

Hybrid Coexistence Feature Example
Cross-Premises Free/Busy and
Calendar Sharing
Creates the look and feel of a
single, seamless organization for
meeting scheduling and
management of calendars
Works with any supported Outlook
client
Hybrid Coexistence Feature Example
Cross-Premises MailTips
Correct evaluation of “Internal” vs.
“External” organization context
Allows awareness and correct
Outlook representation of MailTips
Hybrid Coexistence Feature Example
Cross-Premises Mail Flow
Preserves internal organizational
headers (e.g. auth header)
Message is considered “trusted”
and resolve the sender to rich
recipient information in the GAL
(not SMTP address)
Restrictions specified for that
recipient are honored
Hybrid Coexistence Feature Example
Single OWA URL
Ensures a good end-user
experience as mailboxes are
moved in-and-out of the cloud
since OWA URL remains
unchanged (points to on-premises
“hybrid” CAS)
Log in experience can be improved
by adding domain name into your
cloud URL so that you can access
your cloud mailbox without the
interruption of Go There page

Exchange 2013 CAS/MBX server on-premises
Hybrid configuration in place
 On-premises config, O365 config, federation using MFG, certificates, etc.
 Much of the config is automated by the Hybrid Configuration Wizard

Exchange 2003 is not supported (*)
Delegation Coexistence cross-premises
(delegate permissions are migrated when users are in the same
batch)
Migration of Send As/Full Access permissions
* For Exchange organization running Exchange 2003, consider
using Exchange 2010 SP3 Hybrid deployment
