Creating a Linked Exchange Account

This process supports customers that require completing their AD migration before their Exchange migration by creating a linked Exchange account. This allows users to log into their mailbox that still resides in the source Domain, using their target credentials.

After an account has been migrated, the computer ReACL’d and Cutover to the target, follow these steps in order to link the target account to the Exchange mailbox still residing in the source.

• In the Migrator Pro for Active Directory Console:
  1. Run the Action on the migrated user accounts “Enable on Target/Disable on Source”.
  2. Execute Sync in Migrator Pro for Active Directory for that Directory Sync Pro for Active Directory Synchronization Profile.
  3. Run the “Mark as Migrated” Action on the above user accounts.
  4. Filter on the “Migrated” column as “True” and verify only the accounts to be actioned are in the grid.
  5. Export the Migrator Pro for Active Directory Grid to a CSV.

• On the Source Exchange server:
  1. Download the script file to a local directory and rename BT-ConvertMBX-to-Linked.ps1. The script can be obtained by contacting Support.
  2. Copy the updated CSV created from export of the Migrator Pro for Active Directory grid to the same local directory.
  3. Run the following Exchange PowerShell command – replace items in red date with actual data.

.\BT-ConvertMBX-to-Linked.ps1 –InputCsvPath c:\temp\Export.csv –OutputFolder c:\temp\outputlog –SourceDomainDC E2E-DC1.DOM1.E2E.dom –SourceDomainGC E2E-DC1.DOM1.E2E.dom –TargetDomainController QA-E2E-DC1.QA-Dom1.QA-E2E.dom

Results:

Log output will also be created in the directory specified in the PowerShell command.

Verification:

• Check the following AD attributes:
  1. msExchMasterAccountSid of the source account should contain the target account objectSID value.
  2. Check that the legacyExchangeDN on the both the source and target account has not changed.
• Check the mailbox using Outlook
  1. Log in to computer using target account.
  2. Launch Outlook.
  3. Outlook should launch without prompting for credentials (should us pass-through authentication).
  4. Check that any additional proxyaddress’ are still present on the source user mailbox.
  5. Spot check in Outlook for the retention of signatures, tool bar edits, etc.

Additionally:

• Once all of the above has been completed and verified, migrate the mailbox to the target Exchange and verify that it is still accessible.
