I would recommend following the design guides. I have worked on several customers where if the initial installer would have followed the SRND they wouldn't need me to <font style="BACKGROUND-COLOR: #ffff00">hire</font> me to solve their problems. <br>

<div dir="ltr"><font face="Arial" size="2">Scenario:</font></div>
<div dir="ltr"><font face="Arial" size="2">Unity 5.0 UM server at HQ site talking to Exchange 2007 Partner server. Users homed on 2007 server as well as an additional Exchange 2003 server at HQ. These users function correctly and everything is great.</font></div>
<div dir="ltr"><font face="Arial" size="2">I also have a remote site that has an Exchange 2003 server in the same AD domain. Unity UM at HQ can not deliver voicemails to users homed on that remote server. TAC states that the reason is that MAPI is timing out to this remote Exchange server. Extended pings show an average of 40 - 50 ms response times. According to the design guide, MAPI requires less than 10 ms response times. Bottom line is TAC's recommendation is a Unity server next to any Exchange server that homes user's mailboxes. I see that in the design guide and can appreciate that, but this is an expensive undertaking for a site that only has 20 users on that remote Exchange server.</font></div>
<div dir="ltr"> </div>
<div dir="ltr"><font face="Arial" size="2">So my question is does anyone have any alternate suggestions, or working scenario of this setup? What are my options?</font></div>
<div dir="ltr"><font face="Arial" size="2"></font> </div>
<div dir="ltr"><font face="Arial" size="2">1. Unity UM server at remote location with networking to HQ Unity.</font></div>
<div dir="ltr"><font face="Arial" size="2">2. Move remote Exchange server to HQ and force users to access Exchange over WAN.</font></div>
<div dir="ltr"><font face="Arial" size="2">3. Move remote user's mailboxes to HQ Exchange server.</font></div>
<div dir="ltr"><font face="Arial" size="2">4. Any others?</font></div>
<div dir="ltr"><font face="Arial" size="2"></font> </div>
<div dir="ltr"><font face="Arial" size="2">Any advice or suggestions would be greatly appreciated.</font></div>
