Hi, I setup an co-existence setup with Exchange 2010 and Exchange 2013, moved test mailbox it was working (using ECP) but OWA was not working after upgrade of Exchange 2013 CU7 upgrade. I tried reset virtual directories but no luck. now none of the Exchange virtual directories in working.
Can you please provide me troubleshooting steps to solve this issue? also during troubleshooting i was trying to open " web.config file from using notepad "C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa" unfortunately all config files turns with notepad icon (not sure related to above issue but still thought of giving here).
any help would be much appreciated.
Thanks, Karthikeyan R
