Error Message

Failed: Could not connect to server

The absence of EVAnon virtual directory on any Enterprise Vault storage server can cause this issue.

On the affected user machine:

1. Make sure the EV Outlook Add-in is the same version as that of Enterprise Vault (EV) in the environment.

2. Make sure the External URL configured on the Enterprise Vault server is used. This can be checked from Vault Information:

TESTING CONNECTION
HTTP connection OK    http://External URL/EnterpriseVault (Status: 0x12)

On every EV server hosting archives - Create EVAnon Virtual Directory:

1. Under the \Program Files\Enterprise Vault directory, create a new text file named "Exchangeservers.txt"
2. Open the Exchangeservers.txt and add the IP Address(es) of any Enterprise Vault proxy server that has been nominated to handle external requests. This is the server or servers that the external URL points to.
3. Save the Exchangeservers.txt in ANSI format.
4. Create the EVAnon VD by running the following script under a command prompt, within the \Program Files (x86)\Enterprise Vault\ Directory:

cscript owauser.wsf /domain: /user: /password:

where
 = Domain name of Anonymous Account in Short format (Ex. "Domain" not "Domain.com")
 = Anonymous Account Name created in Step 1.
 = Anonymous Account password.

Notes:
a. Do not include the <> or quotes in the cscript.
b. Run the cscript logged in as the Vault Service Account (VSA), which is a Local Administrator.
c. If EV is installed on Windows Server 2008, it is recommended to open cmd.exe by right-clicking Run as Administrator.
d. The OWAUser.wsf must be run on every EV server which is performing Exchange Mailbox Archiving.

The OWAUser.wsf creates the following footprints on the EV server:

a. Registry
Anonymous Account
HKCU\Software\KVS\EnterpriseVault\AnonymousUser
OWA Web Application Alias (by default this will be EVAnon)
HKLM\Software\KVS\Enterprisevault\Install\OwaWebAppAlias

b. Internet Information Services (IIS)
The EVAnon VD will have the following settings:
Directory Security:
- Authentication and access control - Anonymous only
- IP Address and domain name restrictions - Denied Access 

Note: The EVAnon VD will be set to Denied Access by default and each of the IP addresses from Exchangeservers.txt will be configured as exceptions.

Once the OWAUser.wsf script is run and the EVAnon VD is created, it is required to restart the Enterprise Vault Admin Service and Synchronize all mailboxes. Restarting Services allow EV to be aware of the recent registry changes and Synchronizing all Mailboxes will apply these changes to the hidden mailbox messages.
