Client Profile Updating Utility 5.9 - Administration Guide


During migration, Migration Manager for Exchange moves mailboxes from the source Microsoft Exchange server to the target Microsoft Exchange server. Before users can start working with the new target mailbox, their Microsoft Outlook profiles must also be updated.

The Client Profile Updating Utility (CPUU) 5.9.0 allows you to update these profiles automatically and transparently. The utility is used to update end-user Microsoft Outlook profiles settings, migrate additional features of user mailboxes and finally switch the profiles from the source to the target Exchange server once the user's mailbox is migrated and switched either manually or by the Migration Manager's Mail Agent.

CPUU supports Microsoft Outlook 2013/2016/2019 and Outlook for Office 365. It can be used in conjunction only with the following products:

  • Migration Manager 8.15 or later
  • On Demand Migration for Email


TIP: For details how to use CPUU with ODME, see Working with On Demand Migration for Email


Throughout this document, the following terms are used:

Source servers: the Exchange servers from which the email data is migrated

Target servers: the servers to which the email data is migrated

Console: the computer on which Migration Manager for Exchange is installed

Hereafter, unless a specific Exchange version is meant, "Exchange" denotes Exchange 2013, Exchange 2016, Exchange 2019 organizations, servers, mailboxes, etc.

Configuring and Running the Client Profile Updating Utility

To configure CPUU, create one configuration file (.INI) and three batch files for it using the Client Profile Updating Utility Configuration wizard. Include the resulting files in the logon script for the domain users. When a user logs on to the network, CPUU starts automatically on their workstation with the configuration saved in these files.

Note: If the target is Microsoft Office 365, you have to provide all users with their Office 365 passwords before CPUU switches Outlook profiles. Otherwise, the user cannot log on to their mailbox and get an access to their emails after the switch.

On a workstation, CPUU processes all the Microsoft Outlook user profiles that you selected to be processed when you set up your configuration files. A profile is processed whether or not it is set as the default for Microsoft Outlook. When updating Microsoft Outlook profiles, CPUU looks for a correspondence between the source and target recipients, using the custom attribute populated by the Directory Synchronization Agent.

Caution: CPUU stops Microsoft Outlook or other MAPI clients if these applications are running.

Offline Microsoft Outlook profiles are also updated in accordance with the settings you made when you specified in the INI file. CPUU can process either all offline profiles or only the profiles for the remote users whose mailboxes were added to Remote Users Collections. For information about Remote Users Collections, refer to the Migration Manager for Exchange documentation.

Take into account, the following conditions must be met for CPUU to work properly:

  • CPUU must have an ability to connect to source and target Exchange server in Online mode. Therefore the online mode profile usage by users must not be disabled. Refer to Microsoft article on how to turn on Cached Exchange Mode for details.
  • CPUU requires the Exchange Autodiscover service to be properly configured and run in your Exchange organization.

Supported Configurations

The Client Profile Updating Utility supports the vast majority of client computer configurations. Specifically, all mail clients and operating systems listed below are supported in any valid combinations.

However, only those Exchange Server and Outlook combinations are supported that are also supported by Microsoft. For a list of Outlook versions compatible with your Exchange Server, refer to the Exchange system requirements.

See Client Profile Updating Utility Release Notes document for a complete list of supported configurations.
