Book into Outlook during the call, not after it
Heyfon reads your live Outlook availability while the caller is still on the phone, offers slots that genuinely exist and writes the appointment straight into the calendar your team already works from.
How it works
Connect Outlook
Authorise the calendars Heyfon should read and write, per team member if needed.
Set your rules
Working hours, appointment durations, notice periods and buffers.
Heyfon offers real slots
Live availability read during the conversation.
Event created and confirmed
The appointment appears in Outlook and the caller receives a written confirmation.
One calendar, not two systems
If your team runs on Outlook, a booking tool with its own separate calendar creates exactly the problem it was meant to solve: two places to check and a gap between them. Heyfon books into the Outlook calendar your team already lives in, so what the phone agreed and what your team sees are the same thing.
- Reads live Outlook availability rather than a copy
- Creates the event with the caller’s details attached
- Respects working hours, notice periods and buffers
- Prevents double-booking across people and resources
- Reschedules and cancels in conversation
Works alongside Google Calendar
Businesses rarely standardise perfectly. If part of your team is on Outlook and part on Google Calendar, both are supported, so you do not have to migrate anyone to get the phone answered properly.
