Delete an existing address or repository by highlighting it in the list and selecting Delete from the menu. Click "Yes" to confirm the delete.

Check usage first
Open Used to see which people, sources, or tasks use the address or repository. If you only want to remove it from one person or source, remove that connection instead of deleting the address or repository for everyone.
Make a backup before deleting several entries. See Used Lists for how to remove an address or repository from one person or source.
