Please enable the ability to edit contact information within Contacts under Calls without going back to Outlook to edit a contact.
One currently has to go into Outlook to edit a contacts and contacts are not immediately sync'd between the two applications. Please allow more edit functionality within Teams and sync between both Outlook and Teams when a contact is edited in real time.

There is no reason why Teams can't open the Outlook contact to allow the full editing experience.
