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 *.domain.com doesn’t match the name returned by the autodiscover service server.domain.com

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:*.domain.com 

You can verify the changes you have done by running

Get-OutlookProvider

    Hi,

    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,

    Rich
