Exchange 2013 RMS Shared Identity user FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 not found

Today I was re-installing Exchange 2013 into an Active Directory forest The schema was already extended with the Exchange 2013 schema extensions.

When installing Exchange 2013, installation of the Mailbox Transport role failed with the following error:

Error:
The following error was generated when “$error.Clear();
if ( ($server -eq $null) -and ($RoleIsDatacenter -ne $true) )
{
Update-RmsSharedIdentity -ServerName $RoleNetBIOSName
}
” was run: “RMS Shared Identity user FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 not found.”.

FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 is a Exchange 2013 built in arbitration user account which must exist in every Exchange 2013 environment. The GUID never changes, it is always “4c1f4d8b-8179-4148-93bf-00a95fa1e042”.

The setup failed because someone deleted this user account from Active Directory!

How can we get it back?

You have two ways to get this mailbox back. If you have a computer on your network with the Exchange 2010 management tools installed, you can create the user account using powershell with the following command:

New-Mailbox -Arbitration -Name FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 -UserPrincipalName FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042@default_accepted_domain

For more information on this see Microsoft KB978776

What happens if you do not have exchange management shell installed on any computers? Well there is another way to get this account back. This account is originally created when you prepare the domain/schema. If you run setup.com /PrepareAD on your domain it will re-create this account for you. See below:

Free e-learning course – Virtualizing Microsoft Exchange 2013 on VMware vSphere 5 Fundamentals

This self paced free eLearning course illustrates why organizations need to consider virtualizing Exchange 2013 on VMware vSphere. This course focuses on Exchange design prerequisites and considerations, when virtualizing Exchange 2013.
It also describes design, sizing, and implementation guidelines and best practices, that should be followed as part of a structured design and implementation methodology.

The course consists of three modules:

  • Introduction to Virtualizing Microsoft Exchange 2013 provides an overview of the challenges that organizations typically face when deploying Microsoft Exchange 2013 on physical hardware, and how these challenges can be addressed by virtualizing Exchange on VMware vSphere. This module also describes the benefits that organizations can realize by virtualizing Exchange 2013 on the vSphere platform.
  • Designing the Virtualized Exchange Environment evaluates the prerequisites for designing an Exchange 2013 solution when deployed in a virtualized environment. This module also covers the design considerations and guidelines for designing and sizing Exchange 2013 on vSphere.
  • Implementing the Virtualized Exchange Solution covers various implementation options that should be considered when virtualizing Exchange 2013 on the vSphere platform. This module also discusses several implementation considerations that should be factored into an Exchange 2013 design. Finally, this module discusses how to monitor and test the performance of Exchange 2013 on VMware vSphere.
