Clearing the Matches for Hybrid Accounts

In some cases, you might want to remove the mapping for individual accounts. It might happen when fixing the result of erroneous matching or fine-tuning the outcome of a previous task. To clear unwanted matches, create a special matching task.

  1. Open Accounts and select the hybrid accounts for which you want to remove the mapping.
  2. Click Match Accounts and select Clear existing matches option. Click Next to proceed.
  3. Schedule when the task will be started. See Task Scheduling for details. Click Next to view task summary.
  4. Name the task and check selected options. Click Finish to save or start the task depending on schedule option selected.

NOTE: Once the task is complete, the matched accounts will revert to the New status and the matching is cleared for selected source and target hybrid account pairs.

You can see a task status on the Tasks screen. For more information refer to details panel in the bottom of the screen.

When the task is finished, encrypted information about matching is removed from the custom directory attributes of selected target accounts. See Configuring Hybrid for details.

Migrating Hybrid Accounts

Caution: Don’t start the migration before the discovery and matching tasks are finished.

When the hybrid is configured and enabled, it is time to migrate source users synchronized with Azure AD (hybrid accounts.) Create a new migration task:

  1. Go to the migration project Dashboard in case you use new migration UI. In case you are using classic experience or you are already on the account migration Dashboard, go to step 3.
  2. Click Accounts widget.
  1. Open Accounts.
  2. Select the hybrid accounts you want to migrate. Make sure, the source user accounts are assigned valid licenses.

TIP: Use Searching, Filtering or Using Collections to quickly navigate through the list of accounts. Environment filter help you to select users synchronized with Active Directory.

  1. Click Migrate Accounts and provide your domain name instead of default *.onmicrosoft.com, if necessary.

NOTE: The custom domain name must be set up on the target tenant. See Quickstart: Add a custom domain name to Azure Active Directory for details

  1. Provide the distinguished name of on-premises target OU for migrated accounts, e.g., OU=SubOu,OU=Custom. By default, the container: CN=Users is used, but you should define your custom organizational unit.

NOTE: Target object will be moved in specified target OU even in case it resides in another target OU

  1. Click Next to proceed.
  2. Schedule when the task will be started. See Task Scheduling for details. Click Next to view the task summary.
  3. Check selected options and name the task. Click Finish to save or start the task depending on schedule option selected.

The migration task is created. You can track its progress in the Tasks, view the summary on the Project Dashboard or monitor alerts and notifications in the Events.

IMPORTANT: On Demand Migration copies passwords of on-premises users synchronized with Azure AD to target on-premises OU during migration, but created objects will be blocked (sign-in not allowed). Incoming mail will be forwarded to mailbox on the source until mail migration is completed for the migrated hybrid user accounts.

Domain Coexistence

Mergers and acquisitions are often accompanied by the unification of brands and corporate identities, including the unification of email addresses. However, the full transition from source to target tenant might take a considerable amount of time. To close this gap, On Demand Migration offers the domain coexistence services, allowing your employees to send mail from new addresses and access cross-tenant data before the migration is finished. The following services are currently available on account migration dashboard:

  • Address Rewrite Service seamlessly changes the source users' email flow, as if they're already fully migrated to the target tenant. The outgoing mail addresses are substituted with the target ones, while all incoming mail is automatically redirected to the source mailbox. The address rewriting can be started once the account is matched or migrated, giving you time to prepare and migrate mailboxes without a rush. Address Rewrite Service requires additional licensing.
  • Calendar Sharing allows users from the source and target tenants to see each other's free/busy information.

Address Rewrite Service

Address Rewrite Service substitutes the "From", "To" , and "Cc" addresses in the outgoing emails with the addresses from the target or source tenant depending on selected address rewriting scenario. All incoming mail is automatically redirected to the source or target mailbox according to specified mail forwarding direction. You can specify the users that are processed by the service, for example, only turn it on for Sales and Marketing team members. Address Rewrite Service requires additional licensing.

IMPORTANT: The service only works with accounts that have pairs in the target tenant. Mailbox provisioning is not required, mail users are also supported. Check the documentation on matching or migrating accounts.

Basic Address Rewriting workflow consists of the following steps:

# Step
1 Select Scenario for Address Rewriting
2 Provision Address Rewrite Service
3 Add mailboxes to address rewriting
4 Optionally: add Address Rewrite Service's IP address to the target DNS SPF record
5 Enable address rewriting. You can disable address rewriting at any time or turn off address rewriting for individual mailboxes
Address Rewrite Service Workflow

Address Rewrite Service is intended for creating a coexistence space for domains in which all the email messages coming from the source or target mail domain will look alike they was send from the unified mail domain according the selected settings. Address Rewrite Service will take all the necessary steps for creating this coexistence space in Exchange online environment including creating and managing all necessary connectors, mail flow rules, mail-enabled users and groups both in source and target environments, leaving on behalf of administrator only adding or removing source mail user to this coexistence space and activating / deactivating Address Rewrite Service.

The basic mail message flow in domain coexistence with Address Rewrite Service looks like:

Unified mail domain on the target tenant

  1. When user sends an email as user@source domain mail user it redirected to Address Rewrite Service server in case it is addressed to the external recipients.
  2. Address Rewrite Service receives email from user@source domain, check mail user eligibility to make address rewriting and then process it by rewriting @source mail domain to @target mail domain for every address of users added to coexistence space. These addresses in "From", "To" and "Cc" of the email message are rewritten for all external recipients. Then Address Rewrite Service pass the processed email message to target Exchange Online environment. Internal recipients that reside in source receive this email message with unchanged addresses.
  3. Target Exchange Online sends message to external recipients as it was sent by user from @target mail domain, all addresses of users added to coexistence scope in "From", "To" and "Cc" are rewritten for external recipients.
  4. External recipient doesn’t aware about @source and replies (or create a new email) to the @target mail user.
  5. When the reply or a new mail arrives to target mail domain it will be forwarded to the source. Source recipient gets message as it was natively forwarded from target Exchange online environment from corresponding user@target email user

Unified mail domain on the source tenant

  1. When user sends an email as user@target domain mail user, it redirected to Address Rewrite Service server in case it is addressed to the external recipients.
  2. Address Rewrite Service receives email from user@target domain, check mail user eligibility to make address rewriting and then process it by rewriting @target mail domain to @source mail domain for every address of users added to coexistence space. These addresses in "From", "To" and "Cc" of the email message are rewritten for all external recipients. Then Address Rewrite Service pass the processed email message to source Exchange Online environment. Internal recipients that reside in source receive this email message with unchanged addresses.
  3. Source Exchange Online sends message to external recipients as it was sent by user from @source mail domain, all addresses of users added to coexistence scope in "From", "To" and "Cc" are rewritten for external recipients.
  4. External recipient doesn’t aware about @target and replies (or create a new email) to the @source mail user.
  5. When the reply or a new mail arrives to source mail domain it will be forwarded to the target. Target recipient gets message as it was natively forwarded from source Exchange online environment from corresponding user@source mail user
