Outlook Web Access (OWA) allows administrators to setup themes. I’ve noticed a lot of people configuring custom OWA themes these days. And when they do, they are always annoyed when users change the theme back to the default. So, let’s disable theme selection using the set-owavirtualdirectory cmdlet.
Here, we’ll do so on a server called krypted, on the default web site, for the default owa virtual directory using the -identity option. The option we’ll use is -themeselection enabled and we’ll set it to $false:
set-owavirtualdirectory -identity "krypted\owa (default web site)" -themeselectionenabled $false
To set it back, just swap $false for $true:
set-owavirtualdirectory -identity "krypted\owa (default web site)" -themeselectionenabled $true
