Set-CSUserAcp question



I’m trying to customize the outlook invite message generated when you click the “online meeting” button in outlook

To do that, I use the Set-CsUserAcp command to choose the numbers and pin code I want to appear in the mail.

If I use the “-Url” parameter of the command, the href link to find other numbers is customized too.

The issue is when I click the “Meet now” button in the lync 2010 client. The meeting doesn’t start with the error :

An error occurred during the online meeting. When contacting your support team, reference error ID 400 (source ID 239).

If I look in the server log, I can find this warning :

The error doesn’t occurs If I don’t specify the Url parameter

The error occurs with any url


Do you know what I do wrong or what I forget to configure ?

Thank you very much for your help
