I was able to uninstall the mailbox role smoothly without affecting the production environment, we do have a CAS Array so I assume if there was any stopping of Exchange services the other CAS server was handling requests. &nbsp;<br />
<br />
One simple tip is to click uninstall in add/remove programs not change -- change will leave all installed roles greyed out.<br />
<br />
Thanks!

During the set up of our Exchange environment one of the CAS servers had the mailbox role installed on it. &nbsp;Our set up is this:<br />
<br />
Two CAS servers in an Array<br />
Two Mailbox servers in a DAG<br />
<br />
I need to remove the mailbox role off of one of those CAS servers -- do I just run setup and remove the role? &nbsp;How will the environment be affected while this is running? &nbsp;Can I do this during normal hours or should I schedule downtime for it?<br />

Thanks!<br />
