This topic explains how you can use the Exchange Management Shell to back up and restore the Internet Information Services (IIS) metabase data that a Client Access server uses to store Microsoft Office Outlook Web Access Virtual Directory configuration data.

Important:
The script and procedure included in this topic is an example of one possible way to complete this task. Before you use these techniques in a production environment, test them in a lab environment.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Server Administrator role and local Administrators group for the target server. For more information about permissions, delegating roles, and the rights that are required to administer Microsoft Exchange Server 2007, see Permission Considerations.

Before you can perform this example restore procedure, you must create a script in the Exchange \bin folder that is similar to the following example:

$ErrorActionPreference = 'stop'
$savedprops = @(
'DirectFileAccessOnPublicComputersEnabled',
'DirectFileAccessOnPrivateComputersEnabled',

$vdir = import-clixml $args[0]

'Recreating "' + $vdir.name + '"' + ' owa version: ' + $vdir.owaversion
if ($vdir.owaversion -eq 'Exchange2007') {
new-owavirtualdirectory -website $vdir.website -internalurl $vdir.internalurl -externalurl $vdir.externalurl
}
else {
new-owavirtualdirectory -website $vdir.website -owaversion $vdir.owaversion -name $vdir.displayname -virtualdirectorytype $vdir.virtualdirectorytype
}
$new = get-owavirtualdirectory $vdir.name
'Restoring properties'
foreach ($prop in $savedprops) {
if ($prop -eq 'ExchwebProxyDestination' -or $prop -eq 'VirtualDirectoryType') {
continue
}
$new.$prop = $vdir.$prop
}
$new | set-owavirtualdirectory

Note:
In the following procedure, this script is named restorevdir.ps1.

Procedure

To back up the IIS configuration of a Client Access server

Run the following Exchange Management Shell command:

get-owavirtualdirectory "owa (default web site)" | export-clixml owa.xml -depth 1

To restore the IIS configuration of a Client Access server

Run the following Exchange Management Shell command:
```
restorevdir.ps1 owa.xml
```
