Outlook Web App couldn't initialize.%n%nA base theme couldn't be found. The base theme must be in a folder with name = "%1".

Explanation

This Error event indicates that Microsoft Office Outlook Web App did not initialize because the Outlook Web App base themes folder referenced in the event description does not exist. The base folder contains images and cascading style sheets that are used to control the default appearance of Outlook Web App for your organization. The base folder is also used by other custom Outlook Web App themes if they are installed. By default, the base folder is located in C:\Program Files\ Microsoft\Exchange Server\V14\ClientAccess\Owa\<version>\themes\.

User Action

  • To resolve the error, replace the themes folder and the default subfolders with the files and folders that are located on the Exchange Server 2010 DVD. By default, those files and folders are located in the \Setup\ServerRoles\ClientAccess\owa\<version>\ folder of the Exchange 2010 DVD.

  • Contact a Microsoft Support professional to resolve this issue. To contact a Microsoft Support professional, visit the Exchange Server Solutions Center. In the navigation pane, click Assisted Support Options and use one of the assisted support options to contact a Microsoft Support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.
