<div class="content wysiwyg-content">
We have just change our exchange to a new exchange host and put all the details into outlook 2013 client<br />
DNS records have been changed<br />
These clients are working fine but every few minutes outlook keeps trying to connect to old exchange account and if the users cancel the hostedmail address in the outlok profile is changed to a different address<br />
When outlook is reopened it cannot connect to the new exchange because it has the old exchange registered in the hostedmail connection<br />
When this is change back then exchange works<br />
<br />
How do I get rid of the connectivity to the old exchange on the users pc ?<br />
A new outlook profile does not do it
