How to Use Acrobat Mail Merge Plugin on a Terminal Server
Question details
The user needs to configure an Evermap MailMerge plugin for Adobe Acrobat on a terminal server and restrict its usage to exactly 10 licensed users.

- Product
- Adobe Acrobat, Evermap MailMerge
- Device & OS
- Windows Terminal Server
- Scenario
- Setting up restricted access for a PDF mail merge plugin in a multi-user terminal server environment.
- Observed behavior
- The user wants to deploy a third-party PDF mail merge plugin but needs to restrict its execution to 10 specific named or concurrent users to comply with licensing agreements.
Ensure you have administrative privileges on your terminal server and access to the End User License Agreements (EULA) for both Adobe Acrobat and the Evermap plugin.
Verify Licensing and Restrict Access via System Policies
Because Adobe and third-party plugins handle licensing separately, you must confirm deployment terms with the plugin vendor and use Windows server tools to restrict user access.
Adobe Acrobat cannot natively restrict third-party plugin usage to a specific number of users on a shared server. The management of these licenses depends entirely on the plugin vendor's policies and your server's access control configurations.
Reach out to Evermap support directly to confirm if their End User License Agreement allows terminal server deployment and whether the 10-user limit applies to named users or concurrent sessions.
Open the Group Policy Management Console on your Windows Server. Navigate to Application Control Policies and create an AppLocker rule that allows only a specific Active Directory security group (containing your 10 licensed users) to execute the plugin's specific .api or .exe files.
Ensure that your base Adobe Acrobat installation is properly licensed for a multi-user terminal server environment, as standard standalone licenses usually do not permit terminal server virtualization.

Frequently Asked Questions
Does Adobe Acrobat Standard support mail merge natively?
No, Adobe Acrobat Standard does not have a native mail merge feature. Users typically need to purchase third-party plugins like Evermap or upgrade their workflow using alternative software to handle document merging.
Can I limit plugin access to specific users on a Terminal Server?
Yes. While the PDF software itself might not offer this feature, system administrators can use Windows Group Policy (GPO) or AppLocker to restrict read and execute permissions for the plugin's folder to a designated user group.
Are third-party Acrobat plugins covered by my Adobe license?
No. Third-party plugins are developed and licensed independently. You must purchase, manage, and verify terminal server deployment terms directly with the respective third-party developer.
