<div class="content wysiwyg-content">
We have an older Windows 2008 server that is scheduled for replacement in a few months. &nbsp;There is a certificate that has expired on 6/16/2016. &nbsp;When end users open Outlook they receive a pop-up with the expired certificate requiring attention even though they are now using MS Office 365 for email hosting. &nbsp;The server is a domain controller with Active Directory and File Sharing that is no longer running Exchange.<br />
<br />
Is there a specific service that can be disabled to stop the expired certificate issue?<br />
<br />
Any recommendations are appreciated.
