I am getting an overlap alert when I try to create a new call. What does this mean?
Zoho CRM lets you create as many calls and meetings as you want. The default call duration is 15 minutes and the default meeting duration is 1 hour. If you schedule a call at 5:00 pm and another call at 5:10 pm, then you will get an overlap alert, because there is an overlap on the calendar between the calls.
You can proceed to schedule the call or meeting, despite the alert. You can also change the default duration of a call or a meeting at any time.
Navigate to Calendar > Options > Preferences to change the duration.
