We are using exchange 2007 &amp;&nbsp;recently we installed a separate exchange 2013 in our environment. When we move the mailbox from 2007 to 2013, we have the following issue<br />
I) The user keep prompted for username/password<br />
ii) Require to re-create the outlook profile <br />
iii) Randomly outlook profile crashes &amp;&nbsp;requires to re-create the profile<br />
<br />
In Exchange 2013 env, we have Mailbox server ( which has CAS role) and a separate CAS server. Can we have CAS role installed on mailbox server as well as a separate server?<br />
<br />
Thx
