Event ID 64 – Failed to read and update the Outlook Web Access configuration settings after re-create the Outlook Web Access-related virtual directories

Use these command:

Remove-OwaVirtualDirectory "owa (default web site)"

New-OwaVirtualDirectory -name "owa" -WebSiteName "Default Web Site" –InternalURL https://internalURL/owa -ExternalURL https://externalURL/owa

Hope this helps,
Shree

I have the same error with :
- Remove-OwaVirtualDirectory "owa (default web site)"  --> not found
- New-OwaVirtualDirectory -name "owa" -WebSiteName "Default Web Site" –InternalURL -https://internalURL/owa -ExternalURL https://externalURL/owa --> "owa" already exists
- get-OWAVirtualDirectory | remove-OWAVirtualDirectory  
- remove-owavirtualdirectory "server.company.local\owa (default web site)" --> not found

If I type the command get-OWAVirtualDirectory, I have nothing

I have always the problem

then you have a problem with you IIS metabase, you need to download the metabase explorer to fix this issue

get the metabase explorer from http://support.microsoft.com/kb/840671


install it then start Metabase Explorer. To do this, click Start, All Programs, IIS Resources, and then click Metabase Explorer.

Expand the LM key, right-click the DS2MB key, and then click Delete.

I have installed Metabase Explorer and Expand the LM key, but I have not the DS2MB key.

Screen Print here : http://dl.free.fr/tutVsQxLE

it would be hard to tell without having IIS metabase to play with at hand ATM

try expanding the w3svc "folder" or the IISadmin one can you find OWA virtual directory anywhere ?

I have OWA virtual directory in W3SVC / 1 / ROOT / owa

http://dl.free.fr/bJpx0LAAy

great delete it !

Ok I delete OWA virtual directory from metabase explorer.

I type the command New-OwaVirtualDirectory -name "owa" -WebSiteName "Default Web Site" –internalURL https://internalURL/owa -ExternalURL https://externalURL/owa

Or the command New-OWAVirtualDirectory “owa (default web site)”

And I have this error :

did you try to restart the server ? restart IIS?

I have restart the server and IIS et the problem is the same. Same error.

are you running 2008 sp2 or r2 ?

what exchange rollup ?

also please make sure that Windows Update and Windows Module Installer services are enabled and started

It's 2008 R2.

I have start the Windows Management Instrumentation service and the command New-OwaVirtualDirectory -name "owa" -WebSiteName "Default Web Site" –internalURL https://internalURL/owa -ExternalURL https://externalURL/owa WORK !

Now when I go to the address to https://server/owa, I have a blank page instead of the authentification.

I have a second problem with blank page in OWA

I am afraid this is a totally different issue, I would suggest you open another question for it
