OWA2010 Problem after installation of Exchange 2010 SP1 Rollup1

Not open for further replies.


Yesterday I installed the rollup1 of exchange 2010 sp1.

Now I have problems with OWA 2010.

After the OWA-Login I receive the following error messages:

Outlook Web App konnte nicht initialisiert werden.

Es wurde kein Basisdesign gefunden. Das Basisdesign muss sich in einem Ordner mit einem Namen = "base" befinden.

Outlook Web App konnte den folgenden Designordner nicht laden: C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\\themes\violet

Die folgenden Dateien fehlen: premium.css, gradienth.png, gradientv.png, csssprites.css, csssprites.png, csssprites2.css, csssprites2.png

The english translation would be:

OutlookWebApp could not be initialised. No base design was found. The base design should be located in a directory named "base".

On the exchange server the eventids are 26 and 116. The event source is 'MSExchange OWA'.

Kind regards,

Please confirm that the custom theme you are using ('violet') is present at the location mentioned;

C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\\themes\violet

Could be that the theme is in 'another' themes location like;

C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\owa\<previous version>\themes\violet

You can simply copy the theme to the correct location.

Furthermore, check if the correct permissions are set on the theme's folder.

When you ran SP1 RU1 originally, did you run it as an elevated account?


I ran it as part of windows update. I'm not sure if this means that it runs as an elevated account.
