Autodiscover/Outlook anywhere fails when using a wildcard certificate

A very common issue faced with people who buy a wildcard certificates is that Autodiscover and Outlook Anywhere will not work because the Certificate Principal Name * doesn’t match the name returned by the autodiscover service

This issue is a pretty easy fix it is enough to run from Exchange Management Shell to match the Certificate Principal Name with the setting returned by the autodiscover service.

Set-OutlookProvider -Identity EXPR -CertPrincipalName msstd:* 

You can verify the changes you have done by running

    I am using Exchange 2010 SP1 (Multi-Tenancy). One Organization out of 9 I currently have configured has this issue. What would be the best way to set the Outlook Provider for this 1 Organization?

    Thanks in advance,
