Below you will find answers to common questions related to the CodeTwo Exchange Rules Pro licensing model:


See our website for information on pricing, ordering and the support contract.

How many licenses do I need?

CodeTwo Exchange Rules Pro is licensed per email address and the licenses are sold in packs. You need to purchase a license pack that will cover those email addresses in your organization that you want to benefit from the program. Note that if users in your organization use aliases or shared mailboxes, the number of email addresses may be higher than the number of actual users.

For example, you can buy a pack of 44 licenses that will cover 44 email addresses used by 37 users.


The number of Exchange servers that handle your mail flow does not affect pricing. See this section for further information on licensing in multi-server environments.

Do I need to buy the program for all mailboxes in my organization?

No. You can buy only as many licenses as you need. Note that the licenses are assigned to email addresses and not mailboxes (or users) in general.

How can I buy licenses?

You can buy licenses for CodeTwo Exchange Rules Pro on this website.

How many licenses are currently in use?

You can check the number of currently used licenses and see the list of email addresses that are licensed by clicking the Server Monitor button. This will open the Server Monitor window (Fig. 1.).

How can I buy more licenses?

If the number of licenses is insufficient for your needs, you can purchase an extension pack. Go to the order form and choose Additional licenses.

After buying additional licenses, the license count will be updated automatically in the program in about an hour. If you want to speed up the update, complete the steps from this section.

How many licenses do I need if I have several servers processing mail (multi-server environment)?

Since the CodeTwo Exchange Rules Pro licensing model is based on the number of email addresses that benefit from the program, using several Exchange servers does not increase the price you pay for the program. However, each Exchange server instance requires a separate license key.

Please include information about the installation in a multi-server environment while placing your order, in the comment box. After completing the purchase, you will receive as many license keys as you have Exchange servers.

Note that the Exchange Rules Pro Service (the component responsible for processing mail) must be installed and activated on every server with the Mailbox role.

Instructions on how to install the program in a multi-server environment are available here.

Instructions on how to activate it are available here.

How do I activate the program?

Once the order is completed, you will receive a license key (or license keys, if you use more than one Exchange Server with the Mailbox role) that will upgrade the program from the demo version to the full version. Learn more

How can I upgrade from version 1.x?

The upgrade for the CodeTwo software is provided at additional cost and involves buying an upgrade license pack. Once you purchase an upgrade pack, please refer to this article for instructions on how to upgrade the program from version 1.x to 2.x.

Do I have to pay extra for the updates within the same version of the program?

No, you can update the application with all point releases at no additional cost. For example, if you are a paying user of CodeTwo Exchange Rules Pro 1.0, you can update the software with all installers versioned 1.x at no cost. However, if you want to use the newer, 2.x version, you need to pay for the upgrade.

I already have a product from the CodeTwo Exchange Rules family. What is the cost of migration to the Pro version?

The pricing for migrating from CodeTwo Exchange Rules to the Pro version can be found on the product’s website.

Can I extend the trial period?

If you want to test the program for longer than 30 days before purchasing it, please contact our Technical Support.

Do I have to renew the license annually?

No. Licenses for CodeTwo Exchange Rules Pro are perpetual. You do not need to renew them after 12 months.
