Duplicates in Outlook

I have Outlook 2007 and had to create a duplicate calendar and contact list in order to solve a sync problem with my phone. Now I would like to delete the originals but when I right click one, the "delete" is grayed out. Any help would be appreciated. Thanks, David

 

Think you created a new calendar/contact list and trying to delete the old one?

See bottom text in this link, hope that helps

Same if you created a new address book, delete the old one.

If you tried above and that's what is grayed out, try this if you imported the duplicates, works the same for both contacts and appts.

In Outlook 2007, right clicking the calendar or contact list that I want to delete is totally grayed out and the third choice makes no sense to me. Can it be explained another way so a novice like me (aka dunce) understands? Thanks

 

Think you're trying to delete the primary folders and you can't do that. Only thing you can do is the last link above, which is clean them out, then move the secondary back to the primary folders since all is working again.
