Released: Update Rollups for Exchange 2007 & Exchange 2010 and Security Updates for Exchange 2013
Hi
after install RU2 for SP3. have problem with owa:
Client Access server "https://mail.mydomain.com/owa", running Exchange version "14.3.158.1", is proxying Outlook Web App traffic to Client Access server "mailserver.localdomain.com", which
runs Exchange version "14.2.347.0". To ensure reliable interoperability, the proxying Client Access server needs to be running a newer version of Exchange than the Client Access server it is proxying to. If the proxying Client Access server is running a newer
version of Exchange than the Client Access server it is proxying to, the proxying Client Access server needs to have an Outlook Web App resource folder (for example, "<Exchange Server installation path>)ClientAccessowa8.0.498.0" that contains all the same
versioned resource files as the Client Access server it is proxying to. If you will be running Outlook Web App proxying with mismatched server versions, you can manually copy this resource folder to the proxying Client Access server. After you copy this resource
folder to the proxying Client Access server, you need to restart IIS before proxying will work.
