In order to avoid double booking, we need to ensure that all the relevant calendars are connected under your account to check for availability. **Note:** By default Salesmate checks for the available slots under your primary and the in-built system calendar. ### **How to select Additional Calendars** In order to select multiple calendars, please follow the below steps: * **Navigate to the** More option from left sidebar menu * **Click on** Meeting Scheduler * Under **Actions** on the top right corner select **Select Calendars For Availability** mceclip0.png * A pop-up dialogue box would open up prompting you to **Select Calendars For Availability** . * Selecting one or more calendars from the available list of calendars will share your availability with visitors and will avoid double booking. mceclip1.png * Select from the list of calendar options under the **dropdown** menu, which will allow you to select * multiple calendars from your selected calendar account under **Calendar Sync**. * After you have made the required changes, hit **Save** . * Now the availability for new meetings would be checked under all the selected calendars to check for the slots.
