Microsoft.Exchange.Data.Storage.NotSupportedWithServerVersionExceptionPosted: July 16, 2015
Under a Coexistence scenario with Exchange 2007-Exchange 2013
Some users are reporting they cannot access OWA.
When a user tries to log on to Outlook Web Access (OWA) 2013 and the user mailbox is stored in an Exchange 2007 Database the browser displays the following message and user is not able to access to his mailbox.
After investigation I found it´s a client side caching issue.
Clear the Internet Explorer cache (cookies and web site data) and restart the browser.
