Quip – How to Delete a Contact

You should have a look at Lifehacker full guide to clean up Gmail Contacts.

Some topics they cover that could help you:

• clean up duplicates
• export and import csv

I'd say that for 200 contacts, the easiest way is to:

1. export to CSV
2. keep the contacts you want (delete the unwanted rows)
3. delete all your gmail contacts
4. import the clean and fresh CSV to Google Contacts

UPDATE:

Outlook’s “People” feature lets you integrate contacts from Facebook, Google and Twitter, as well as from other sites and sources.

Note that I said “integrate,” not import. The difference is that when you “connect” to the social services, to use Microsoft’s term, it doesn’t really import them. In other words, it doesn’t copy the address book. It merely points to it.

If you want to delete a contact “imported” from Facebook, for example, you can’t do it from Outlook.com. You have to do it from Facebook. Only contacts created in the Outlook.com “People” area can be deleted from Outlook.com.

I haven’t imported any contacts so I don’t know if they behave differently (I assume they shouldn’t), but can’t you just delete the respective contact(s)? Just select it/them from the left-side list and a delete button will appear in the upper menu.
