Outlook 2007 Views reset to default

One of our end users asked me about why his Outlook 2007 would not keep the changes he made to his views and it kept turning on the reading pane. I googled it and I found that clicking Start > Run > and key in "outlook /cleanviews" and logging out of Outlook and back in cleaned up his corrupt views which caused Outlook to keep defaulting to the original. Now any changes he makes are saved!
