<div class="content wysiwyg-content">
 I have an Exchange 2010 SP1 installation, and when any user goes into OWA they receive the following error:<br />
<br />
&quot;An unexpected error occurred and your request couldn't be handled&quot;<br />
<br />
This happens whenever clicking any of the following OWA objects:<br />
Any folder within the mailbox<br />
The Options dropdown button<br />
The Find Someone search box<br />
The &quot;Refresh&quot; button that Checks for New Messages<br />
The Delete, Move, Filter, View buttons<br />
Clicking New will open a new window to write a new message<br />
Within the Calendar, the View buttons do not function<br />
<br />
If I manually navigate to the /ecp Control Panel I have no issues. &nbsp;Outlook Anywhere, ActiveSync, etc all work fine. &nbsp;Just seems to be within OWA.<br />
<br />
I've already applied RU2 and ultimately RU3v3. &nbsp;I've double checked vDir permissions, redirect, etc in IIS against other Exchange 2010 installations and cannot locate the cause of the issue.<br />
<br />
I've turned up diagnostic logging and still nothing relevant. &nbsp;IIS logs show nothing out of the ordinary either. &nbsp;Exchange BPA... nothing. &nbsp;I've also recreated the OWA vDir from the Exchange Console.<br />
