If a token is generated using a passphrase that contains a $ character, and if the passphrase is provided inside a double-quoted string, the DUA install will exit with an error message.
Workarounds:
1. Use single-quotes to contain the passphrase.

2. Use a passphrase that does not contain this special character.

2. Escape the $ character with a backtick character in front of it, e.g. for a passphrase abc$123 enter abc`$123

PST file configuration in New Outlook is not migrated by DUA. Microsoft support for PSTs in New Outlook remains 'partial.' No API or alternative method is available to DUA to migrate PSTs during reconfiguration. Quest will continue to monitor the Microsoft 365 roadmap for further updates to PST support. 567073
If running On Demand Desktop Update Agent as Administrator, it is not possible to update OneDrive. This is a Microsoft OneDrive limitation. 498466
On Windows 10, if the Desktop Update Agent reconfiguration task for OneDrive is interrupted before the restart, after restart a message displays that a folder cannot be found. 529144

The OneDrive reconfiguration step drops all OneDrive connections on a computer when a restart is needed when switching one profile with the Preserve Existing Folder option enabled.

Accounts that were not switched will need to log in to OneDrive again. This affects computers with multiple user profiles.

When migrating "roaming" signatures with Outlook O365, even though the registry keys get set, the signatures are not used by Outlook. 411635

If the Desktop Update Agent is stopped suddenly (for example, due to an unexpected computer restart or stopping the agent through Task Manager), On Demand Migration will not be updated with the in-flight results.

If progress in the agent is stopped between steps by choosing Cancel, the state of each step is reported to On Demand Migration and the On Demand Migration dashboard will reflect what was completed.

Desktop Update Agent version 2.5.1 (Technical Preview)

September 2025

New Features Issue ID

The agent now runs silently in the background and automatically polls On Demand Migration for switch tasks at regular intervals. Users no longer need to manually start the agent; after installation it will automatically start on the next sign-in or reboot, and will open on the desktop to prompt for processing when action is required.

Processing can also be postponed by end users for several minutes or hours, providing greater flexibility.

NOTE: On the Switch Application Task's Schedule tab, the default option has changed from Run Now to Schedule.

Migration administrators should schedule Switch Applications tasks so that they are not run until prerequisite migration project steps have been completed and their help desk is ready to support users, if necessary.

Additionally, migration administrators can now view installed Desktop Update Agent reports directly in the On Demand Migration interface, improving visibility and management of agent deployments.

Desktop Update Agent version 2.4.1

December 2024

Enhancement Issue ID
Selection of the Outlook variant (Classic or New) to reconfigure

Desktop Update Agent  needs to close and restart Outlook during the reconfiguration process, Which Outlook variants to reconfigure will be based on the following:

  • If New Outlook and/or Classic Outlook is configured and running when DUA starts, those Outlook variants will be stopped, reconfigured, then restarted.

    • If both variants are configured but only one is running when DUA starts, only the variant that is running will be reconfigured.

  • If neither New nor Classic Outlook is running when DUA starts, DUA will check the user's registry keys for the UseNewOutlook setting to determine which variant the user prefers. Classic Outlook or New Outlook will be reconfigured according to the value of that switch.

    • If the UseNewOutlook registry key is not present, DUA will check the computer for configured Outlook profiles (Classic) and reconfigure Classic Outlook if found.

      DUA will also check the computer for a user account for new Outlook, and reconfigure New Outlook if that account is found.

    		•

      NOTE: Either Outlook variant must be started to complete reconfiguration. In this scenario it is possible that the Desktop Update Agent will start both Outlook variants.

  • If none of these conditions match, Outlook configuration will be skipped.

After the Desktop Update Agent completes, if the Outlook variant that was reconfigured is not the one expected or preferred by the user, a second run can be performed to correct this. The migration administrator can set up a new Switch task for any affected users. The user should ensure their required Outlook variant is running and then manually start the Desktop Update Agent. DUA will then reconfigure that Outlook variant based on the criteria listed above.

The agent now logs the On Demand Migration endpoint that it will contact. This will help identify misconfigurations related to tokens and the different processing regions. 459448
Agent enhanced to support use of the Desktop Update Agent with On Demand Migration Hybrid Exchange. 464123
Resolved Issues Issue ID
If an incorrect passphrase is entered in the agent installer, a warning is issued and the installation will not complete. This avoids a situation where the agent would be installed, but no token would be stored. 446216
When switching multiple profiles on one computer, the status for the PowerShell Script steps could incorrectly reflect a previous run. The status now resets correctly for each profile. 449831

In some domain move scenarios involving a vanity domain, the Desktop Update Agent is unable to locate the source profile, because the source email and User Principal Name known to On Demand Migration will have changed as part of the move process.

In this situation, the Desktop Update Agent may try to create a new profile using another discovered email address, which may result in an incorrectly configured user profile. As a result, Outlook might not be able to start and will report that the current set of folders cannot be opened.

This change also resolves a OneDrive issue related to the same scenario.

 464126
Added digital signatures to the Microsoft-derived scripts included with the Desktop Update Agent, which are used in the Office 365 application licensing step. 467724

Incident response management

Quest Operations and Quest Support have procedures in place to monitor the health of the system and ensure

any degradation of the service is promptly identified and resolved. On Demand relies on Azure and AWS

infrastructure and as such, is subject to the possible disruption of these services. You can view the following

status pages:

System requirements

Before you begin a migration project and agent deployment, ensure that your systems meet the following minimum requirements.

General Requirements
  • Client has been licensed for On Demand Migration.
  • Access to a Global Administrator account for each Microsoft 365 tenant.
  • Disable policies that prevent Outlook Profile, OneDrive for Business, and Microsoft Teams application changes or creation.
  • If applicable, users have been provided new or temporary password for the account in the new target destination Microsoft 365 tenant.
  • Source and target users have matching attribute values to identify and pair objects together for mailbox and OneDrive content synchronization.

TIP: Try Password Sync for On Demand Migration Active Directory to keep your migrated hybrid users synchronized so when they are moved, they keep their existing password.

License Requirements

Before starting a migration, each target user account must be licensed for each application that will be reconfigured using Desktop Update Agent. The following licenses are required:

  • Exchange Online if configuring Outlook profiles.
  • SharePoint Online if configuring the OneDrive for Business application.
  • Microsoft Teams if configuring the Microsoft Teams application.

NOTE: On Demand Migration can automatically assign these licenses to target user accounts during the email and OneDrive migration process.

Software Requirements

NOTE: If OneDrive for Business, Microsoft Teams, Outlook, or Office are not installed on the workstation, those applications will be skipped and not impact any other applications present during the reconfiguration.

The minimum version requirements for software installed on user’s workstations:

  • Windows 11, or Windows 10 with a valid Microsoft Windows Extended Support Update (ESU) license
  • .NET 4.7.2 or higher
  • Outlook 2016 (32-bit or 64-bit) or higher. The Outlook client must also conform to the Microsoft version requirements for the applicable Exchange target version.
  • OneDrive for Business (Most recent updates recommended)
  • Microsoft Teams
  • Microsoft 365 Apps (Office Click-to-Run Version Only)

NOTE:

  • Microsoft Office Professional Plus is not supported for Office license reset.

  • LTSC versions of Windows and/or Office are not tested or supported by DUA.

Network Requirements

The minimum network requirements to run Desktop Update Agent:

NOTE: During this process, the Outlook Profile will be copied to a new Profile directed to the target account. Due to this configuration, a new OST download will occur based on each user's current cache settings, if enabled. To avoid network congestion try disabling or curtailing the cache settings to a lower amount of data then slowly increase it as needed. This can be accomplished through policies.

Supported Authentication

On Demand Migration Desktop Update Agent supports environments that use:

  • Active Directory Federation Services (AD FS)
  • Single Sign On (SSO) with mixed authentication modes, such as:
    • Modern Authentication (ADAL)
    • Forms Authentication
    • Windows Integrated Authentication
