Bridge to Nova

After you have upgraded to Outlook 2007 from the earlier outlook versions, you will get suprise to see that all categories from contacts, have been converted to color categories globally.

So you will see in calendar, tasks, and you’ve been so annoyed that, you want to reset to default color categories? You can’t find any options in Outlook 2007 to reset to default categories. If you delete one by one, it could take a long long time.

So, the easiest way is :
Start menu–>> RUN—>> and enter “c:\program files\microsoft office\office12\outlook.exe” /cleancategories“

Enjoy your journey with new stylish Outlook 2007!
