Update Address List activity 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. Input variables Table 1. Update Address List input variables Variable Description hostname The hostname of the Exchange server with which the activity interacts. Do not enter an IP address in this variable. domain The name of the Exchange server's assigned domain. identity Name of the address list to update. domainController Fully-qualified domain name (FQDN) of the domain controller that writes to Active Directory. whatif A check box that indicates if the activity should stage the changes without applying them. Use this variable to test your activity settings before using the activity in a live workflow. When this variable is selected, the Exchange server does not make any changes but indicates if the command would succeed or fail. You can review any messages from the Exchange server using the ECC queue. Output variables Table 2.
