Need to go my own way but suggestion helped.

<div>
<div class="content wysiwyg-content">
I have just move one of our clients over to a Hosted Office 365 account and all works ok but I have one issue. &nbsp;When connecting there outlook desktop client to the exchange server I got a popup alert that said the certificate is either expired or not setup yet. &nbsp; I can just click yes and proceed but this popup occurs every time you open outlook. &nbsp;The client used to have an SSL certificate through GoDaddy for credit cards but did not use it anymore and it has expired. &nbsp;The hosting company they use said they would probably need to get a CSR from the Exchange server that hosts the Exchange but I do not host the Exchange Microsoft does so I guess my question would be has anyone ever ran into this before and if so what could be done to get rid of the alert. &nbsp;I called Microsoft but they were not really any help. &nbsp;Any help would be appreciated thanks.
