I find it very easy to use, simple interface with all my contacts in one place so that i can easily schedule meetings at any time of day or night for work purposes as well personal ones too! The only thing is sometimes when you open up your calendar its not always clear which events are scheduled until after they have already taken place but other than this everything has been great!! This software does help me streamline scheduling outbound calls into our sales team members schedules through Outlook 365/Outlook On-Premise both internally within an organization & externally via Salesforce CRM system (Sales Cloud).
