  • 1 minute to read

    • The Update Address List activity adds or removes users from the specified address list and immediately applies any cached address list changes to the server.

    Use the optional parameters variable to specify which users to add or remove. This activity implements the Microsoft Exchange Update-AddressList command.

    To access this activity in the Workflow Editor, select the Custom tab, and then navigate to Custom Activities > Exchange > Address List.
    Note:
    This activity replaces an Exchange activity by the same name available in releases prior to Geneva. If you have a workflow created in a previous version that uses the deprecated activity, your workflow will continue to work normally after upgrading to Geneva. However, all new workflows must use the custom version of this activity. This activity was built with the PowerShell activity designer, which gives workflow administrators the ability to store input and output variables in the databus.
