App Error Something went wrong - OWA Webapp
We run an Enterprise Vault 10.4 server and are moving to Exchange 2013. I have registered OwaWebApp on a new Exchange 2013 user. When accessing the Enterprise Vault button on a vaulted item I get the error
App Error Something went wrong and we couldn't start this app. Please try again later or contact your system administrator.
I suspect this might be related to the URL and certificates. We currently use an internal name for the evserver as everver.domain.local and do not want to change this. However for webapp to work, we wanted to ensure SSL was enabled. I created a DNS alias fro evserver.domain.com and have registered a star cert on the evserver testing both http and https to the enterprisevault directory. No issues here.
I do notice however when I goto the URL for the Webapp i.e http://evserver.domain.com/EnterpriseVault/OfficeMailAppManifest.aspx?LegacyMbxDn=mylegacydn I see an XML page showing the internal server name (https://evserver.domain.local) this will not match with my SSL cert.
1. Does the EV server need to be accessible externally for remote users to access EV content from owa? or perhaps the CAS server accesses the evserver internally and just retrieves the content to be displayed.
2. we use evserver.domain.local internally. Does this cause any issues accessing items? I suspect that if this indeed uses the internal name on https there will be cert errors.
The command I used to register the webapp
New-App -mailbox $Mbx.LegacyExchangeDN -Url ("https://evserver.domain.com/EnterpriseVault/OfficeMailAppManifest.aspx?LegacyMbxDn=" + $Mbx.LegacyExchangeDN)
Thanks
I was actually able to get the email to retrieve now by fixing our SSL cert binding in exchange web services per the following article
