Predefine Selection of Exchange Mailbox Stores


You can customize the way Adaxes determines which database to select by default when manually creating Exchange mailboxes for users. You can specify which mailbox databases can be used and how to distribute new mailboxes between them. For example, you may want the mailbox database that contains the least number of mailboxes to be always selected by default.

Using Adaxes it is possible to automate provisioning of Exchange mailboxes. For details, see Automate User Provisioning.

To configure options for selecting mailbox databases, you need to use Property Patterns. Adaxes provides built-in Property Pattern User Pattern that is by default applied to all user accounts. In this tutorial, you will learn how to use the Property Pattern to customize the way mailbox databases are selected by default.

  1. Launch Adaxes Administration Console.

    Expand Adaxes service \ Configuration \ Property Patterns \ Builtin and select User Pattern.


  2. Right-click the Exchange Mailbox Store property and click Edit in the context menu.

  3. Select which databases can be used for new mailboxes and how to determine which one to select by default.

    When done, click OK.

    When creating an Exchange mailbox for a user, only the mailbox stores located in the user's domain are available.
  4. If necessary, modify the template used to generate mailbox aliases.

  5. Click Save changes.

Any changes made to built-in Property Patterns can be discarded. To do it, right-click a Property Pattern and click Restore to Initial State in the context menu.

Different Patterns for Different Users

By default, Property Pattern User Pattern is applied to scope All Objects.



This means that the Property Pattern can be used to configure the same settings for all users in all domains managed by Adaxes. If you want to apply different settings for different Organizational Units or domains, you need to delete the Exchange Mailbox Store property from Property Pattern User Pattern, and then create a separate Property Pattern for each OU or domain.


  • Right-click Property Patterns, point to New and click Property Pattern.

  • Enter a name for the new Property Pattern and click Next.


  • On the Object Type page, select User and click Next.


  • On the Configuration page, configure options for a property and click Next.


  • To define the scope of activity for the Property Pattern, click Add.


  • In the Activity Scope dialog, select the following items:

    • Specific Domain - select to apply the Property Pattern to all users in a domain.
    • OU or Container - select to apply the Property Pattern to users in an Organizational Unit or container.
    • Group - select to apply the Property Pattern to members of a group.

      Assignments over group members are not applied during user creation.
    • Business Unit - select to apply the Property Pattern to members of a Business Unit. To select a Business Unit, open the Look in drop-down list and select the Business Units item.

    You can exclude specific Organizational Units, Business Units, groups, and domains from the activity scope of the Property Pattern. For example, if you've assigned the Property Pattern over the whole domain, but do not want it to apply to a specific Organizational Unit, you can exclude the Organizational Unit from the activity scope. To exclude an object, select the Exclude option in the Assignment Options dialog box.

    • Click the object you want to exclude.

    • In the Assignment Options dialog, select the Exclude option.


    • Click OK.
  • When done, click Finish.
