If a contact has multiple deals, which deal are email activities associated to?

Why can't I see the activities I've written on a record?

Does changing or deleting an activity category delete the existing Activities?

How can I see who I collaborated with on an activity after the activity is created?

Why is my email activity not displaying within my records yet?

How do I find the notes I wrote in my tasks or events?

Can I edit the name of a system field?
