Set a default calendar in Front Calendar
If you have multiple Google or Office365 accounts connected to Front, you may have multiple calendars that you can schedule meetings on in Front Calendar, which you will see listed on the left. When you create a new event, your default calendar will be picked, but the calendar dropdown allows you to manually change the calendar that you want to schedule a new meeting on.
To change the default calendar, continue to the instructions below.
Click on your avatar on the top left of Front and choosing Settings.
Click on My preferences on the left and then scroll down to the Default Calendar setting. From here you can use the dropdown to pick the calendar that you’d like new meetings to be scheduled on by default.
Click the Save button on the top right to save your changes. Now when you schedule new meetings, the new calendar will be your default, though you can still manually change it when you create the event.
